McLeod RXT Twin Clutch Toyota 2JZ T56 Trans w/Steel FW 1-1/8in x 26 Spline

The McLeod 6482207M is the RXT twin-disc clutch for one specific swap: a Toyota 2JZ inline-six (the 1993-1998 Supra engine) bolted to a TREMEC T56-family six-speed with a 1-1/8 in. x 26-spline input shaft. If you are building a boosted 2JZ-GTE past what a single-disc clutch will hold, or your current clutch already slips in third and fourth under full boost, this is the ceramic-faced, track-capable kit in McLeod's 2JZ-T56 lineup. It ships complete with a billet steel flywheel, so you are not adapting a factory Toyota flywheel to a GM-pattern gearbox.

What the RXT twin clutch does in a 2JZ-to-T56 swap

A twin-disc clutch splits the clamping job across two 9.688 in. (246 mm) discs with a floater plate between them. Doubling the friction surfaces lets McLeod hold far more torque than a single disc of the same diameter, while the smaller discs and steel floater keep rotating mass reasonable. On the RXT those discs are segmented ceramic, which is what moves the rating up to about 1,100 hp. The trade-off is engagement: ceramic grabs harder than organic, so expect a quicker bite point and more chatter if you slip it in a parking lot. The pressure plate is a diaphragm design and the discs use a solid hub, which also transmits more driveline noise than a sprung street hub. The flywheel is machined for a 115-tooth ring gear and is zero balance, the right choice for the internally balanced 2JZ.

If you want to see why builders step up to two discs at all, our guide on twin disc vs single disc clutches walks through holding power, pedal effort and street manners.

Symptoms that point you to this kit

• Engine rpm flares under boost in higher gears while road speed lags: classic clutch slip once a 2JZ makes big torque.
• A single-disc kit that held at stock boost but gives up after a bigger turbo, injectors or E85.
• Burnt-friction smell after a launch or a pull, glazed or heat-checked flywheel face on teardown.
• You are planning a 2JZ swap onto a T56 Magnum and want the clutch sized for the power level from day one rather than replacing it twice.

How to confirm you need it

Before blaming the clutch, rule out hydraulics: a release bearing that is not fully retracting, or a misadjusted slave, keeps the pressure plate from applying full clamp and will mimic a worn disc. Our clutch slipping guide covers the checks in order. Then size the clutch to the gearbox. TREMEC rates the T56 Magnum at 700 lb-ft, so a 1,100 hp clutch is only worth it if the rest of the driveline is built for it; compare options in our T56 Magnum vs TKX breakdown.

Fitment

This listing is the 2JZ engine pattern, T56 input of 1-1/8 in. x 26 splines, steel flywheel, 115-tooth ring gear, 0 balance. It is not a direct fit for the factory Supra W58 or V160 gearbox; those need a different McLeod kit. 2JZ-to-T56 conversions are not all built the same, because adapter plates, bellhousings and pilot arrangements vary by kit maker. Count the input splines on your gearbox before ordering (there is a 24-spline listing in this family, the RXT HD 6482207HD), confirm your starter matches a 115-tooth ring gear, and if anything is unclear send us your engine, gearbox and adapter details before you buy. The softer organic version of this kit is the RST 6482207.

Install notes

• Included: two discs, floater, pressure plate assembly, billet steel flywheel and an alignment tool. Not included: release bearing, pilot bushing or bearing, and mounting hardware, so source flywheel and pressure-plate bolts for your crank and flywheel thread.
• Twin-disc clutches need correct release travel. Set the hydraulic release bearing air gap to McLeod's instruction sheet; a GM-style T56 can use a slip-on hydraulic bearing like the McLeod 1400-22 slip-on bearing if your bellhousing is set up for it.
• Torque flywheel bolts in a cross pattern with thread locker, then pressure plate bolts evenly so the floater stays aligned.
• Bed the ceramic discs in with gentle starts and no hard launches for the first few hundred miles; our clutch break-in guide explains why.
• Pulling the T56 apart while it is out? The 9379A gear puller handles fifth and sixth gear removal.

Will the 6482207M bolt to my factory Supra six-speed?

No. This kit is built for a 2JZ engine mated to a T56-family gearbox with a 1-1/8 in. x 26-spline input. The factory V160 and W58 gearboxes use different input shafts and need a different kit.

How much power will the RXT twin hold?

McLeod rates the RXT line at up to about 1,100 hp. Keep in mind TREMEC rates the T56 Magnum itself at 700 lb-ft, so the gearbox may become the limit before this clutch does.

Does it come with a throwout bearing or pilot bushing?

No. The kit includes the two ceramic discs, floater, pressure plate, billet steel flywheel and an alignment tool. The release bearing, pilot and mounting bolts are separate and depend on your adapter and bellhousing.

Is the RXT too aggressive for a street car?

It is drivable, but the segmented ceramic discs and solid hub engage quicker and transmit more noise than organic. If the car is mostly street driven under about 800 hp, the RST 6482207 version is the smoother choice.

What ring gear and balance does the flywheel use?

The steel flywheel carries a 115-tooth ring gear and is zero balance, matching the internally balanced 2JZ. Confirm your starter engages a 115-tooth ring before installing.
