W-Series Transmission Adapter for 1UZFE Swap FITS ALL KNOWN W SERIES ALUMINUM HOUSING TRANSMISSIONS

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!

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

There are a number of bearings that look exactly the same as these on the market, but are notoriously cheap and low quality. We recommend this one specifically.

Required adapter fittings are optional. Please note we cannot provide -3 bleed fittings the bleed side will always be -4 with our kits.

Although they do go out from time to time, we offer OEM quality replacement hydraulic release bearings for our UZ adapter kits using a single disc clutch setup. We've tested a variety of different ones over the years, and found this one to be the most reliable, especially at this price point. This functions as the slave cylinder and release bearing for the clutch, offering a universal solution instead of chassis specific, keeping costs down and require less bespoke parts.

Please note that you will need to remove the GM style fitting by driving out the retaining pin and replacing it with the AN fittings provided with the kit originally. We can also provide replacement fittings as necessary.

Since every swap and chassis is different, let us know the exact line length and fittings needed and we can also have a hose made for you! 

With plenty of different fitments, these flywheel bolts are most likely the ones you need. These are used to bolt the flywheel to the crankshaft. Includes moly lube! Specific fitment includes but is not limited to:

☼ XAT Racing R150, R151, R154 etc. 1UZ/2UZ/3UZ Manual Transmission Adapter

☼ XAT Racing W55, W58, etc. 1UZ/2UZ/3UZ Manual Transmission Adapter

☼ XAT Racing KA24 / SR20 1UZ/2UZ/3UZ Manual Transmission Adapter

Please note these will NOT work with multi disc clutch kits (such as our QuarterMaster twin disc kits). Please reach out to us if you have those applications. These bolts are also meant for the above manual transmission swaps only, not the factory automatic.

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!

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.

The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Great for street, drag, autocross, road racing, pulling, rally and drift.

XAT QuarterMaster 1UZ Twin Clutch Kit

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.
