Toyota, Lexus 3UR-FE, 3UR-FBE 2007-2021 5.7 V8

We have been offering these for a few years now with superb results! These are not simply overpriced regrinds of stock cams. There are machined from new billet cores.

These cams will be for anyone looking to get the most out of their Tundra, Sequoia, LX570, GX460, Land Cruiser, etc. with the 3URFE, 3URFBE, or 1URFE engines. 

If you've already done basic mods like intake, exhaust, and tune, this is the logical next step for you to have some noticeable gains, however you can expect to need at least an upgraded valvetrain to run these. We cannot confirm fitment with the LS460 and GS460 car 1UR-FSE engines. DO NOT expect them to drop in without modifications. We DO make 1URFSE specific cams as well

For the manufacturing process, we start with proprietary cast iron billets, CNC machine the lobes, and finish off with double heat treatment, 5160 induction hardening, and Tufftriding.

Pictured is one set from the actual run of UR cams made!! We have just a few sets left in stock, as these are low production numbers. Once they leave, there may be a few weeks wait time before we get more in. Don't forget to install the "freeze plug" caps at the end of the cams during installation.  

Cam specs for factory cams:
236 duration, 6.36 cam lift intake
236 duration, 6.27mm cam lift exhaust

Cam specs for XAT RACE cams:
282 duration, 7.17 cam lift intake, 245 duration at .050"
286 duration, 7.17 cam lift exhaust, 247 duration at .050"

With the factory rocker ratio, that's 10.76mm of valve lift with our cams! As such, you should verify clearance with your pistons and these cams. In most cases, you may need custom pistons.

We've focused on the 1UZ, 2UZ, and 3UZ engines for many years now, and will continue to develop more and more parts for those iconic V8s. We're also now starting to gear up for the UR market, starting with performance camshafts and a billet dry sump oil pan! We're building this around a 3URFE engine, and suspect it will likely fit the 1UR 4.6 and 2UR 5.0 V8s also. Confirmation will come at a later date.

The pan is being designed to be used in conjunction with the Moroso dry sump oil pump. This kit is being modeled after the TRD UZ V8s one, but being built specifically for the larger UR block.

Please note, this is not a complete bolt on kit. We are developing these still, which will be unique to each chassis. Expect to sacrifice your A/C compressor for this, or possibly have to relocate other engine driven accessories. You will still need the belt driven oil pump, lines, tank, and any other ancillary parts (such as cooler, filter housing, etc.), though these parts will depend on intended use, goals, and budget for the vehicle.

XAT Racing has brought to market our Stainless Steel intake and exhaust valve kits for the TOYOTA/LEXUS 3UR and 1UR engines. If you're building a high horsepower engine, these valves are a must for dealing with the intense heat that a supercharger or turbo will be adding to the combustion process. Swirl polished heads, hardened tips, and chrome plated stems ensure years of durability and performance from these valves. We offer these kits in standard size or +.5mm oversized.

Standard Size kit will include 16x Intake valves at 38mm head size, 16x Exhaust valves at 32mm head size

Oversize kit will include  16x Intake valves at 38.5mm head size, 16x Exhaust valves at 32.5mm head size

These kits fit the TOYOTA/ LEXUS 5.7L 3UR  V8 engine, the TOYOTA/ LEXUS 4.6L 1UR-FE V8 engine found in the TUNDRA, SEQUOIA, GX460, LX570, LANDCRUISER 5.7 and 4.6L, and the LS460 Middle Eastern spec with the 1UR-FE engine.

At long last, aftermarket rods are available for these massive Toyota engines! BC calls these their PRO-H rods (H-beam), and they come in 2 flavors.

For most builds, the 2k version is all that's needed. The ProH2K is rated in excess of 1400 HP and priced for the everyday performance enthusiast who isn't going to the moon, using ARP2000 rod bolts.

Anyone looking to pump it up to the next level would want to opt for the ProH625+ version, which uses Custom Age 625+ fasteners instead of the ARP2000s. They cost a bit more, but they're rated at 2000 HP and should be able to handle anything you can throw at them!

The BC stroker kit for the Toyota 3URFE engine platform incorporates a 108mm stroke, steel billet crank, choice of BC 625+ Pro Series or ProH2K Billet rods. Depending on bore size that you decide, the BC kit will take you up to a 6.80 liters with 100mm bore sleeved block. As usual, each BC kit features custom CP or JE aluminum forged pistons, 9310 alloy wrist pins, ring pack and buttons.  

This kit will stroke your 5.7 3UR to a 6.0! If used in conjunction with the Darton Sleeves, you can get up to 6.8 liters out of it!!

Kit includes stroker crank, set of 8 CP/JE pistons (with rings and wrist pins), and set of 8 BC rods

Working with one of the biggest names in the industry, XAT Racing has commissioned a set of valve springs and retainers made specifically for the 3UR 5.7 V8 from Toyota/Lexus! These arent simply reused springs from a different application, these springs are purpose built to drop in to your 3UR-FE and 3UR-FBE engine. These will fit all 3URs as well, no matter if it is from a Tundra, Sequoia, Land Cruiser or LX570!

Dont forget to opt for the titanium retainers as well! Base price is for springs only.

These are not required when installing our exclusive in house billet cams, but are strongly recommended. We also strongly recommend opting for the titanium retainers to help reduce valvetrain weight and keep everything locked in. After all, you wouldnt want to go through the effort to upgrade the springs just to leave out the retainers, right? You could add them later...if you want to rip your engine back apart again..

This service includes modifying both heads, not just one side. You get a full port job, 5 angle valve job, cylinder head inspection, and the heads get hot tanked for a proper cleaning. We offer this service for all UR engines. Regardless of what chassis your engine is out of, we service them all! LS460, LS600h, LC500, LX570, GX460, Land Cruiser, Tundra, Sequoia, etc.

Please keep in mind that your heads will likely require extra work: heads will typically need to be decked, and you may need other parts replaced such as valve guides. We will keep in touch with you during this process and let you know what your setup needs.

You cannot define every possibility in a single description or for all applications, but 'generally' speaking, what we provide with our Street Cylinder Head Refresh package is great for up to 7,000+ RPM, more RPM would be possible with proper optional valve train.

XAT has teamed up with Manley Performance to provide and develop top level valvetrain parts to build with. Includes brand new Ferrea valve locks as well!

In reality, no matter what purpose/intended use of your build, you will benefit! The truth is unless you are building a 1300HP+ drag car, you can pretty much eliminate any serious deep cylinder head porting. You simply do not gain enough volumetric efficiency by hogging out a ton of metal in the heads, unless you are running a silly-high lift custom cam.

If you live outside of the USA, NO PROBLEM! Please contact us for a shipping quote and we will be happy to help you out! PRICE DOES NOT INCLUDE SHIPPING TO OR FROM US

Nobody else makes these. So why wouldn't we?? XAT now offers billet main caps for the latest Toyota V8s! If you're looking to build the baddest UR on the planet, look no further. Whether you're building a VIP LS, a quick GS, a rock crawling GX, or a beastly Tundra, Land Cruiser, or Sequoia, we can help build and assemble your motor for you to handle however much power you are aiming for! We've installed these on a few built engines now, and we're looking forward to continuing that trend!

Keep in mind, as with all main cap replacements, you will need to have your engine line bored after installing these.

Higher horsepower means more oil demand. When you're running twice or three times the stock power output, you absolutely have to be sure your engine is getting lubricated everywhere it needs to! Especially if you have an aftermarket oil cooler to keep oil temps down! What does XAT do to bring you options for a better oil pump? We take a brand new OEM one, remove all hard edges, radius all corners, enlarge the front main seal drain, and shim the pressure relief valve to give more max PSI. Make sure you get a quality oil pump for your engine, from the professionals at XAT!

Please note that we start with an OEM part, even though it will not say Toyota on the box. We do not use knockoff brands for this, and will not risk an engine on poor quality or questionable parts.

We are only currently able to source 1URFE and 3UR covers also at these prices. If you have a 1URFSE from a sedan (GS460, LS460) you will need to send your front cover and oil pump in.

Please include which year and model you have so we can get you the right version of the kit!

THE BIGGEST, THE BADDEST, MOST EFFICIENT, MOST POWERFUL SUPERCHARGER SYSTEM!!

Counter rotating churros to make your Tundra V8 SING!

Quick version of what you'll need:

• T56 style throw out bearing
• Pilot bushing adapter (included with transmission adapter)
• Nissan 6 speed
• Our flywheel (no other ones will work)
• 300ZX TT clutch
• 3UR serviceable bellhousing with 12 bolt trans flange

Quick version of what you will need:

• T56 style throw out bearing
• Our flywheel (no other ones will work)
• 300ZX TT clutch
• UR serviceable bellhousing with 12 bolt or 14 bolt trans flange
• Pilot bearing (included)
• T56 transmission

As we break into the new era of 1UR and 3UR engines, we have begun development on 6 speed manual swap options. We've developed an adapter plate specific for the UR automatic bellhousings to convert to a manual transmission, in this case the popular Tremec T56 Magnum! This specific plate works on all UR engines, however you will need the matching bellhousing that has the 12 or 14 bolt bellhousing-to-trans-case pattern. The only 1UR bellhousing this does not bolt to is the Land Cruiser/LX460 200 series 1UR-FE with the same 14 bolt pattern as the 3UR engines.

This billet aluminum adapter plate reuses your automatic UR bellhousing. Not all UR engines had a replaceable bellhousing, so you may need to source one from a GX460 or other Toyota/Lexus URs for instance. 

Our flywheel for T56 transmission applications uses the same one as our UR-to-Nissan 6 speed (commonly referred to as the CD009). You will need our in house flywheel, which bolts to your factory flex plate. We are able to keep costs down of this custom billet part by reusing the factory flexplate for a ring gear, instead of supplying an aftermarket one that does not work any better than the factory parts do. T56 transmission not included.

Please note the 1UR-FSE and 1UR-FE 4.6 engines uses a different flywheel than the 3UR-FE and 3UR-FBE 5.7 truck engine. You will reuse your factory flex plate for the ring gear and factory starter engagement.

The T56 style throw out bearing is also used with these kits. These are relatively inexpensive, which helps keep swap-cost down. We also offer a Quarter Master TOB as an option for a higher quality long term investment. 

Twin disc/multi plate clutches will require the use of the QM TOB, it is not optional on the 7.25" and 8.5" twin disc clutches we offer. The QM TOB also requires a Tilton quill tube (input shaft sleeve), which is included as well as the bleed line that is needed if the QM TOB option is selected.

Looking for a clutch for this adapter plate? 

Our "standard" UR Toyota V8 build has no problem holding 800 HP, but we also have options to do well over 1000+ HP!!

We also know the importance of being able to customize your build and have the flexibility to run exactly what your budget allows.

Please note this does not include the core charge. We can easily and quickly source an engine for you, or you can send yours to us for building. We've built countless engines over the years, including multiple builds making more than 1000 horsepower. 

Contact us with your address for a shipping quote! Listing does not include shipping price to or from us

• New OEM oil pump (XAT upgrade optional)
• Block honing with torque plate
• Hot tank/vapor blast block
  
  

Ask us about additional "white glove" service options to really make your built engine stand out!

Ever have an engine come apart at high RPM? Well, we haven't. At least, not due to rotating assembly vibrations. We've partnered with the biggest name in the industry yet again to release an 800+ HP capable harmonic balancer for all 3UR-FE and 3UR-FBE 5.7 liter "big block Toyota" engines. That includes Sequoia, Tundra, Land Cruiser, and LX570.

You will have to grind down the factory washer for clearance on the factory crank bolt for this to fit properly. We typically use a belt sander and hold it at a 45* angle to shave the OD. There is no other easy option for this

Please note this does not work with 6 rib belt 1UR engines. We are still working on a solution for the small block 4.6.

We now stock a special 7" overdrive diameter pulley for high boost applications with a supercharger! A larger pulley while keeping the included blower pulley the same size will spin the blower faster and make more boost. WE STRONGLY RECOMMEND NOT DOING THIS UNLESS YOU HAVE A BUILT ENGINE WITH AFTERMARKET RODS AND A SOLID TUNE. 

These pistons are typically custom made to order, but we do keep a set on the shelf! Let us know how much HP you're running, what compression ratio you are aiming for, if you're boosted or not, and any other pertinent mods. Pictured is an actual piston from a full set we had custom made for our customer.

You will receive all 8 pistons along with the needed rings, wrist pins, pin locks, and paperwork.

Manley 3UR pistons come standard with anti-friction moly coated side skirts (something we recommend for all pistons anyways), high performance chrome piston rings, and the pin locks.

• 2618 high strength material
• Offset wrist pin for quiet start-ups
• .210" wall Premium Chrome Moly pin (Standard Series) or 9310 alloy .210" wall pin (Extreme Duty Series) included
• Pressure balance groove
• Premium Steel top rings and round wire locks included
• Recommended piston clearance .0035" measured .850" from the bottom of the oil ring

All Victory injectors start out as Bosch cores. They are then sized and matched within 1-2% providing exceptional idle quality. All injectors come with a limited 2 year warranty. You will also receive 1 free cleaning within the first 2 years! All injectors are a top feed high impedance injector and a direct drop in on the 1UR, 2UR, and 3UR engines. 

Make sure you select your size from the drop down menu! Price is for a full set of 8. Please keep in mind that you will need to custom make connectors to fit the stock harness because of how tight of a fit it is. We include pigtail wiring for you to do so.

Also fit direct injection FSE heads, however these only replace the port injectors. You keep the factory direct injectors. Tuning is absolutely required when installing these.

High performance ACL bearings for your big block Toyota V8! We use these with every engine build we do. One of the best names in the business

WE HAVE COMPLETION!! First batch of cams have been completed. These are not simply overpriced regrinds of stock cams. There are machined from new billet cores.

These cams will be for anyone looking to get the most out of their Lexus GS460, LS460, Toyota Crown Majesta etc. with the 1URFSE engine or LS600h with the 2UR-FSE (not the GSE in the F cars--RC-F, GS-F, LC500, etc). THESE ARE NOT MEANT FOR THE 1UR-FE TRUCK ENGINE IN THE TUNDRA, GX460, ETC.

If you've already done basic mods like intake, exhaust, and tune, this is the logical next step for you to have some noticeable gains, however you can expect to need at least an upgraded valvetrain to run these.

For the manufacturing process, we start with proprietary cast iron billets, CNC machine the lobes, and finish off with double heat treatment, 5160 induction hardening, and Tufftriding.

Pictured is one set from the actual run of UR cams made!! We have just a few sets left in stock, as these are low production numbers. Once they leave, there may be a few weeks wait time before we get more in

Cam specs for XAT cams:
294 duration, 7.17 cam lift intake, 245 duration at .050"
300 duration, 7.17 cam lift exhaust, 247 duration at .050"

With the factory rocker ratio, that's 10.76mm of valve lift with our cams! As such, you should verify clearance with your pistons and these cams. In most cases, you may need custom pistons.

XAT 1UZ-FE 2UZ-FE 3UZ-FE Torque Hone Plate XAT EXCLUSIVE

High performance ACL bearings for your big block Toyota V8! We use these with every engine build we do. One of the best names in the business

Full bearing kit to rebuild your big block Toyota! ACL does not currently make a thrust washer for the 3UR, so we have been using OEM ones for in house and customer engine builds. 

Includes rod bearings, main bearings, and thrust washers.

Why isn't everyone running a 3UR?! After tearing one down and analyzing the engine top to bottom, we've really come to appreciate the level of engineering that has gone into these engines. It's no wonder they were made for over 15 years! We feel they're extremely underrated, and they also respond especially well to supercharging.

XAT has been building 3URs and developing new parts for years for customers worldwide. We pride ourselves with taking the time to correctly assemble and rebuild every engine, knowing them inside and out. We also are excited to build more and more of these for boost, as our daily driven Whipple supercharged Tundra has become an entirely different beast with forced induction.

Every engine gets hand built to order. Not everyone has the same goals or budget in mind, so we have built everything from mild to wild, including an all out 6.8 liter bored and stroked version!

You will need to send us your engine, or you can use one of our supplied cores. We have a few in stock!

Our "base" engine build handles 800 HP reliably, but we do have a variety of options that you should also consider. If you're not sure if you want them, keep in mind that it's much easier to spend a few extra bucks while we have it and it's apart, than it is to go back in later and add these parts!

Base build includes fully assembled engine, ready to drop in:

• BC ARP2000 rods
• Manley pistons, 10.0:1 compression ratio
• Full OEM new engine gasket kit
• All new timing parts (chain, guides, tensioners, etc.)
• ACL rod/main bearings, OEM thrust washer
• Block honing with torque plate
• Hot tanked engine
• XAT modified high performance oil pump
• Ported intake/exhaust ports
• Valve job
• ARP head studs
• ARP main studs
• Heads bolted to block, timing set
• New valve stem seals

Every engine shipping from us also gets crated in ISPM 15 certified wood crates for international shipment. Your investment needs to be protected, and this is included in the build price

Shipping is not included, you will need to reach out to us with your location and we can get shipping quotes to your address! Ask us about additional "white glove" service options to really make your built engine stand out!

Fits 2007-2015 Tundras and Sequoias with 3URFE and 3URFBE 5.7 liter V8!

We try to keep a set of these in stock, but please be aware there may be a 10-12 week backorder if we do not have a set ready to ship. Feel free to reach out to us to verify stock before placing your order.

Open up your 3UR to more power and torque with these 1.875" (1 7/8") stainless long tube headers! This kit also includes a stainless 3" connector pipe with high flow cats, so you can keep your CEL off and not have a stinky exhaust.

Please note the standard race headers are not road legal; this is an off-road, race only assembly. Don't expect to be able to ship these to California especially! 

If you plan on driving on the street, you will want the GREEN version instead. The race high flow cats are also not designed to be used with a turbo or supercharger. 

Please contact us for availability on your specific needs, so you can plan your build accordingly! Expected wait time is typically 6-8 weeks or longer

Our custom built 3UR engines with oversized bore (looking for 6.8 liters?!) are typically made by JE. We have these custom made to spec, and if you have a specific idea in mind for bore size and options, we can make it a reality!

JE Pistons opened its doors for business in 1947 with one simple objective, to supply the racing community with the highest quality pistons and components available in the marketplace. Although times, people and equipment have changed, their objectives and goals have remained constant. Today, JE is the largest manufacturer of custom forged racing pistons in the world. Offering the shortest lead times in the industry and a 98% order fill rate, JE is the definitive source for all of your high performance needs.

The JE complex encompasses the most modern performance piston manufacturing equipment in the industry. JE’s implementation of the most advanced CNC machining technologies available, emphasizes their commitment to deliver the highest quality pistons, pins, rings and components available today. Industry leading processes like Ultra Crown®‚ a digital three-dimensional piston crown machining process, and Ultra Groove®‚ a machining operation that provides unprecedented flatness of ring grooves (tolerances to within millionths of an inch), are some examples of that commitment.

JE designs are specifically engineered for extreme applications up to, and including, professional competition. In this environment, the higher compression ratios, highest boost or heavy nitrous usage necessitate the higher tensile strength 2618 aluminum alloy. Features: Dome/Dish requires no deburring or preparation and feature smooth flowing radii for excellent flame travel. Pin fitting, wire locks, and rings included

Forced pin oilers from the oil ring; Pin Fitted; Moly Coated Skirts; 3D Dome & Pockets; Pins, Locks all included!

Select your specific UR engine application from the dropdown menu!

For those that need more electricity than the stock alternator can provide, we have teamed up with JS Alternators to offer these custom made to order options! Even better, theyre plug and play, no adapter wiring needed!

JS Alternators also requires their universal Big 3 wiring kit, or otherwise similar wiring upgrades in addition to the factory wiring in order to handle the higher output. The big 3 Wiring upgrade is an ADDITION to your factory wiring.
All factory connections need to remain connected. For protection, it is recommended to add an in line fuse to the positive wire. All grounds must be cleaned to bare metal and properly secured.

Big 3 wires are 1/0 gauge pure copper cables. 1 positive to connect from the positive stud on the alternator to the positive battery terminal. Other 2 ground wires go from the alternator mount bolt to frame/chassis, and negative on the battery to frame/chassis.

Most JS Alternators are custom built to order and typically take 5-15 business days to be built and shipped. All JS alternators have a lifetime warranty on labor, and 1 year warranty on parts.

Hairpin units are commonly called 6 phase. They produce more output at idle and are more efficient than a conventional alternator. JS Alternators hairpin units feature premium bearings to withstand high engine rpm and utilize dual plate rectifier with 12 heavy duty diodes for improved cooling. Hairpin Units are a more reliable alternator to withstand high heat, high demand for car audio, marine, and racing applications.

Although this is one of the most universal parts we sell, it's also one of the most interesting, and one of the few that we sell that has FAA approval for aircraft use! Most people just buy whatever oil filter they find and toss them after use. There's a better option however, especially if you plan on owning your vehicle for many years to come! 

Made in the USA with a billet aluminum housing and a stainless micronic medical grade mesh filter element that is easily serviced and cleaned, this is a great long term solution for your cherished ride. There's a number of advantages that come with using a high quality filter like this, instead of a generic spin on replacement.

• Easily tell the condition of the oil in your engine with every oil change. Instead of destroying an oil filter each time to inspect the contents, you simply wash out and reuse the same filter element.
• Filter element is reusable countless times, and easily cleaned with brake cleaner and/or soap and water
• As time goes by, oil filters become more and more expensive. Do you think your favorite oil filter will be the same price in a few years? It wont take long for this to pay for itself!
• Apocalypse proof! Even if supply chains get interrupted, you can keep on truckin' without having to worry about sourcing a replacement filter for your engine.
• Even if you miraculously somehow manage to damage the filter element, replacement ones are readily available and not expensive
