Clutches And Flywheels

This is a complete kit, with twin disc clutch assembly, install kit (ARP flywheel bolts, clutch hardware), button flywheel, and spacer as needed. 

Which engine? Which transmission? All of them! 

We have a version for your UZ engine, with Z33 / Z34 trans, R154, V160, or W58! The twin disc is recommended for 800rwhp cars for street/drift/endurance. The sintered metallic compound is one of the highest quality materials for clutches. This clutch has slots between the segments to help cool the clutch easier, and extra thick padding to last through an extreme amount of abuse! 

All feedback for this clutch from our many customers over the years has been overwhelmingly positive. Clutch pedal isnt overly aggressive, it can still slip for street driving, yet has no problem holding gobs of power. Here at XAT, we often measure power in gobs. This kit holds "many" gobs. This is the 8.5 inch version we recommend most for street driven cars.

The starter gear includes the ring gear needed to start the car. The much smaller button flywheel has much less rotating mass to deal with and works very well, but has no starter motor engagement. The base kit includes the button flywheel, with an option to have a full size flywheel and clutch combo. The assembled RaceLite clutch and flywheel weighs 22 lbs 14 oz.

If this is your first time with an XAT clutch conversion, you will need the starter gear as well. Otherwise you can opt for the RaceLite flywheel instead and not need the starter gear or the button flywheel. You should be using a 3/4" master cylinder in tandem with the TOB we use.

XAT QuarterMaster 1UZ Twin Clutch Kit

For this setup, XAT started completely from scratch, as nothing beats a purpose built billet part from the ground up! As we continue to partner up and offer more and more options for the increasingly popular Nissan 350Z/370Z 6 speed-known to handle over 800 HP at the wheels without opening it up, we continue to bring custom bespoke and billet parts to replace the aged V160 and R154 options. 

These Nissan trannies have been proven that they are a stout and reliable trans that is inexpensive, readily available, and will be for many years to come. Although the early years proved to be troublesome with the CD001, CD003, and CD005 transmissions, by the CD008 and CD009 revisions, shifting has been improved, smoothed out, and solidified. The newer JK40C 370Z transmissions are also reported to have the same internals carried over from the CD009. 

This will fit all versions of this transmission: CD001, CD003, CD005, CD008, CD009, JK41A, JK41B, JK40C, 1EA0A, and 1EA0B Our light weight flywheel is infinitely rebuildable with replaceable friction surface disc, and at just under 14 lbs, it feels right at home both on the street and at the track. Flywheel bolts get torqued to 80 ft lbs. Dont forget to do so in a cross pattern! Single disc clutch options will be anything "off the shelf" that fits the 300ZX turbo (Z32). 

Please email us if you have ANY questions or need assistance with choosing the right clutch for your build! 

** We sell clutch kits to fit this flywheel, ready to go! ** 

As a quick recap: You will need the UZ V8 automatic bellhousing, if you haven't converted already. We also have twin disc QuarterMaster clutches (7.25" and 8.5" twin disc) and flywheels. We offer a QM throw out bearing for fitment. The twin disc clutch kits do NOT use this flywheel, they use a "button flywheel" instead.

Required ARP Flywheel bolts are included with this flywheel!

Our 1UZ / 2UZ / 3UZ series V8 chromoly flywheel is made form some of the hardest, most durable metal we can source for a flywheel.

Our machine shop gets mad every time we do a production run--they go on and on about how hard the alloy is, takes longer to machine, wears out tooling... Well that's great news if you're planning on abusing your V8!!! This flywheel will take some serious abuse without a doubt, and we have proven it ourselves in our personal cars over a length of time.

Weighing in at just 11 LBS, you will instantly notice your V8 rev up and rev down much faster! This equates to a more responsive throttle, getting to the important parts of your powerband, and more efficient engine braking.

Our flywheel utilizes the proven torque holding clutches of the SW20 MR2 TURBO 3S-GTE. We offer clutch setups to suit everything from a stock engine all the way to to 680 FT/LBS with this flywheel!

When installing our flywheel: you will be required to install the OEM automatic bolt guide on the crank before installing the flywheel. This item is curved--the curve needs to face the engine and fit flat on the crank-to-flywheel mating surface. Please see pictures for more information as well. After installing the bolt guide, torque the included ARP bolt kit to 70 FT/LBS using red thread locker/loctite on the bolts, and tightening in a star pattern, not one next to the other. We also recommend tightening down in 2 or 3 goes as well instead of going from finger tight straight to 70 ft lbs.

This flywheel is meant for our W55/W58, R150/R151, R154, KA, and SR transmission adapters. This will NOT work with our CD009 / JK series Nissan 6 speed adapter!

The SPEC Stage 2 Clutch kit custom made for manual transmission swapped 1UZ, 2UZ, and 3UZ Toyota/Lexus V8 engines holds 398 ft lbs of torque, and is an outstanding upgrade for those with basic mods or even stock powered cars that simply want to be able to hold more power for the future. Features segmented or full faced pure Kevlar disc with steel backing. This lining features excellent drivability like the stage 1, but offers slightly longer life and higher torque capacity. The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Best for street, drag, pulling and autocross.

If you select Z33/Z34 fitment, we will provide you with the Z32TT clutch made to fit with our in house CD009 kits. We chose that clutch specifically to design the kit around.

This XAT flywheel is perfect for those who want a simple and straightforward flywheel for a manual conversion on their Toyota/Lexus V8. Affordable cast flywheel with OEM quality and OEM ring gear. 

Excellent for starter projects and conversions, as well as daily street driving. This flywheel weighs 20 lbs 4 oz. Looking for a bit more performance and less rotating mass? 

Check out the 13 lb XAT Chromoly Flywheel instead!! Our flywheel utilizes the proven torque holding clutches of the SW20 MR2 TURBO 3S-GTE. We offer clutch setups to suit everything from a stock engine all the way up to 680 FT/LBS with this flywheel! 

For installation when using the optional ARP bolt kit, torque to 70 FT/LBS using red thread locker/loctite on the bolts, and tightening in a star pattern, not one next to the other. We also recommend tightening down in 2 or 3 passes as well, instead of going from finger tight straight to 70 ft lbs. This flywheel does NOT require any spacers to bolt on, not even the factory spacer that goes from the crankshaft to the factory flex plate.

This flywheel is meant for our W55/W58, R150/R151, R154, KA, and SR transmission adapters. This will NOT work with our CD009 / JK series Nissan 6 speed adapter! Also not meant to fit international H151 models

ARP Flywheel Bolts for Custom XAT QM Clutches to Z33 Z34 Transmission

XAT Racing is proud to announce the latest single disc in house custom made flywheel option for our many UZ swap kits! Unlike our OEM style and lightweight chromoly flywheels, these aluminum ones are infinitely rebuildable with a replacement friction surface and hardware (included!). They are also tailor made for the UZ Toyota/Lexus V8s from the ground up, not re-purposed from other flywheels!! This flywheel comes in at just over 9 lbs!!

Our aluminum flywheels will use the same 3S-GTE clutches that the other flywheels and our kits utilize. We have a broad selection of choices, some of which are in stock. We will be happy to help and make recommendations for your application!

This flywheel will work with any of our W55, W56, W58, W59, R150, R151, R154, R155, KA, or SR transmission adapters. This will not work with our CD009 or JK series Nissan 6 speed kits. 

No spacers are required to bolt this on, not even the factory one that goes from the crankshaft to factory flex plate gets reused.

Ring gear is already fit, and friction surface is included with order!

If you're using one of our adapter plates to put a Nissan 6 speed behind your 1UZ, 2UZ, 3UZ, 1JZ, or 2JZ as well as our single disc flywheel, you'll need a clutch to put down that power too! This is the clutch we recommend for most conversions and applications that are sticking with a single disc setup.

Rated for 480 ft lbs, but similar versions of this very same clutch has been popular for 600+ ft lbs builds for quite some time. We used this very clutch in the 2JZ '71 El Camino project we built. Smooth, stock pedal feel, and easily daily driveable, yet still capable of holding boosted V8 power.

If you are using an adapter from a different company,we can likely still supply you with the clutch you need. You will need to verify what type of clutch your adapter uses, as not all CD009 adapters use the same clutch. If you're not sure, pleae reach out to us or your adapter's manufacturer.

Transmission fitment includes CD001, CD003, CD005, CD008, CD009, CD00A, JK41A, JK41B, JK40C, 1EA0A, 1EA0B, and possibly more from any 6 speed Nissan 350Z, 370Z, Infiniti G35 and G37.

Kit Includes:
☼ Heavy duty pressure plate
☼ Ceramic 6 puck sprung clutch disc
☼ Alignment tool
☼ Pilot bushing (this is also included with our adapter plates)
☼ Throw out bearing (this does not get used with our adapter kits, we use an internal Quarter Master hydraulic TOB)

An XAT favorite! This is the same clutch we recommend for our CD009 conversion kits, was used in our 2JZ El Camino build, and (as pictured) is running in our TRD supercharged X-Runner!

Kit includes clutch disc, pressure plate, instructions, throw out bearing (we recommend upgrading to the bolt on ClutchMasters hydraulic throw out bearing instead).

Fits all 2005-2015 Tacoma V6 1GR trucks with the RA60 6 speed transmission. Also confirmed to work with the URD flywheel!

Dump your WHOLE LOAD all over our full face! disc clutch. Why pay more for another clutch when this one exists? XAT is proud to announce our budget clutch kit for W55, W56, W57, W58, R150, R151, R154, and R155 fitment (as well as AR5 and KA/SR kits) when swapping to a manual transmission for your Toyota/Lexus UZ V8! We keep them in stock, so if you need it quickly, we can ship it quickly

Finally, a bolt-in clutch pedal bracket for LS400! Designed and produced in the Grindhouse skunk works, XAT Racing has just what you need to be doing clutch kicks in Grandpa's land yacht. This adapter uses a specific Wilwood clutch pedal with remote reservoir available from the dropdown menu! The end product is a 100% bolt-in assembly with many available cylinder bores and adjustable pedal engagement. Fitment has been confirmed on LHD UCF10 chassis (89-94 LS400) only. Contact us for UCF20 and rollcage-mounted options. Please keep in mind these are often made to order and may have a delay in producing them. You will need to have the clutch line custom made of course, depending on transmission used. Let us know what you need for your application and we can supply that as well!

Another way of making life easy when having to replace the factory clutch master cylinder, either from being worn out, or having a stiffer clutch that necessitates a larger bore diameter master cylinder! This new product lets you bolt on most popular aftermarket master cylinders, and is just one more part we're offering to help keep these cars sustainable on the road!

The OEM Toyota Master Cylinder for the clutch has been discontinued! If you want to repair your car correctly (not using cheap parts of unknown origin), you'll want to opt for one of these kits! 

XAT Quarter Master flywheels are only as big as they need to be, so they do not have a ring gear for the starter to engage, meaning you simply need to reuse the factory flex plate. This keeps cost down, as well as unnecessary rotating mass

XAT Racing Toyota Lexus 1GZ V12 Lightweight Billet Aluminum 13.5 lb Flywheel for CD009 Nissan Infiniti 6 speed 350Z 370Z G35 G37 Manual Transmission Swaps

SC300 - SC400 Z30 Clutch Pedal Mount Kit with Pedal and New Master Cylinder and Banjo bolt kit Please note that the optional master cylinder with these kits is not ideal for our 1UZ/SC400 swap kits for W, R, or CD009 transmissions. You will need a 3/4" master cylinder with those.

If you're doing a 5 speed or 6 speed swap on your SC chassis, you're going to need one of these. It's the only affordable, readily available clutch pedal that's a direct bolt in for the Z30 chassis requiring no modifications to the sheet metal on the car to mount it up, only some trimming on the sound deadening under the dash.

The Z30 chassis had factory clutch options so there are good mounting points that they've utilized along with a Toyota Celica ('90 -'93) clutch master for a direct bolt in fitment that clears the Brake booster in the engine bay and sits the pedal nicely in the cab. The main bracket is formed 1/8" steel and the hanging pedal arm is 1/4" steel on a 12mm pivot.

The main bracket is formed 1/8" steel and the hanging pedal arm is 1/4" steel on a 12mm pivot, simple, effective and more affordable the a factory Z30 part.

They've also provided all the bolting hardware for the clutch mount and the master cylinder hook ups including a banjo bolt for better clutch line fitment when using braided stainless line kits.

This kit has an option for the clutch master cylinder, which is not ideal for our XAT swaps, since our kits require a 3/4" master cylinder. We also have clutch line kits for W58 and R154 transmissions.

As a quick recap: You will need the JZ J3 automatic bellhousing, as well as our adapter kit (or SupraStore's), if you haven't converted already. We also have twin disc QuarterMaster clutches (7.25" and 8.5" twin disc) and flywheels. We offer a QM throw out bearing for fitment. The twin disc clutch kits do NOT use this flywheel, they use a "button flywheel" instead.
