McLeod RXT HD Twin Clutch Toyota 2JZ T56 Trans w/Steel FW 1-1/8in x 24 Spline
If your 2JZ is now making more boost than the clutch can hold behind a T56 six-speed, the McLeod RXT HD (part number 6482207HD) is the heaviest-duty member of McLeod's 2JZ-to-T56 twin-disc family. It is a complete package: two ceramic discs, the pressure plate assembly, a dedicated billet steel flywheel, mounting hardware and an alignment tool, built for 1993-1998 Toyota Supra 2JZ engines that have been swapped to a T56. People usually shop for it after a single-disc unit starts slipping in third and fourth gear under full boost, or after a lighter twin-disc has been pushed past its limit.
A clutch holds torque through clamp load multiplied by friction area. A single disc can only gain capacity by adding spring pressure, which makes the pedal brutal. A twin-disc doubles the friction surfaces by stacking two discs with a floater plate between them, so it can hold far more torque at a drivable pedal. The RXT HD goes one step further than the standard RXT: McLeod describes it as the higher-clamp-load version of the RXT, marketed as the RXT 1200 for builds around 1,200 crank horsepower, with ceramic facings and strap drive. On this kit the discs are 9.688 in. (246 mm) segmented ceramic with solid hubs and a diaphragm pressure plate, and the flywheel is billet steel with a 115-tooth ring gear and zero (internal) balance to suit the 2JZ.
The RXT HD sits above two closely related McLeod kits for the same swap: the RST twin (6482207) with organic discs for street-only cars, and the standard RXT twin (6482207M). If your power level does not need the HD clamp load, one of those will give an easier pedal. For background on how two discs change engagement, read our twin-disc vs single-disc comparison.
Rule out the cheap causes first. On a hydraulic setup, a bearing that is set too close or a master cylinder that does not fully return can hold the clutch partly released, which looks exactly like a worn disc. Check that the pedal has free play and that the bearing clearance matches the release system instructions. Our manual vs automatic repair cost guide explains what a clutch job costs in labor so you can plan the replacement properly, and the clutch slipping diagnosis guide walks through a load test.
Swap fitment also depends on your bellhousing or adapter plate and the release system you run, so confirm those before install. Browse more swap clutch options and drivetrain parts in our hard parts catalog.
Torque the flywheel and pressure plate bolts to McLeod's instructions using new hardware, and use the supplied alignment tool so the input shaft slides into both disc hubs without force. Twin-disc assemblies are matched; do not mix discs or floaters between kits. Set bearing clearance carefully because a twin-disc has less release travel to spare than a single disc. While the gearbox is out, inspect the T56 input bearing and front seal. If you are working inside the gearbox at the same time, the T56/TR6060 5th and 6th gear puller saves time, and a fresh fill of manual gear oil such as Red Line MTL 75W80 GL-4 is worth doing; confirm the fluid your specific T56 variant calls for. Bed the discs in with gentle street driving before any hard launches.

The product title lists 1-1/8 in. x 24 spline, but McLeod's own application line for this part number reads 1-1/8 x 26. Count the splines on your T56 input shaft before ordering and include the count with your order if you want us to double check.
All three are McLeod twin-disc kits with a steel flywheel for the 2JZ-to-T56 swap. The RST uses organic discs and is street only, the RXT uses ceramic discs, and the RXT HD adds a higher-clamp-load pressure plate for the biggest power levels, with a firmer pedal as the tradeoff.
No. It includes the twin-disc clutch, billet steel flywheel, mounting hardware and an alignment tool. Plan on supplying the release bearing that matches your bellhousing and release system, plus a pilot bearing or bushing.
No. This kit is built for a 2JZ engine bolted to a T56 six-speed. A stock Supra with the factory transmission needs a different clutch.
McLeod builds it for street and strip cars, with ceramic discs and strap drive. Expect a heavier pedal than the RST or standard RXT, and give the discs a gentle break-in period before hard launches.
