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

McLeod part 6482207 is the RST Street Twin for a 2JZ inline-six bolted to a T56-style six-speed with a 1-1/8 in. x 26-spline input. It is the organic-faced member of McLeod's 2JZ-T56 family: the one to pick when the car is driven on the street most of the time, makes more power than a single disc can hold, and you still want a light pedal and smooth take-offs in traffic. A billet steel flywheel comes in the box, cut for a 115-tooth ring gear at zero balance.

How the RST Street Twin works behind a 2JZ

Instead of one large disc, the RST clamps two 9.687 in. (246 mm) organic discs separated by a floater plate. Two friction faces on each disc means four clamping surfaces in total, so the pressure plate can hold a turbocharged 2JZ without the crushing spring load a single heavy-duty plate would need. That is why McLeod advertises a lighter-than-stock pedal feel on this line. Organic full-face linings slip in progressively and release cleanly, and McLeod uses a Blanchard-ground floater with multiple drive straps to keep rattle down at idle. McLeod rates the RST Street Twin family at up to roughly 800 hp, which covers most single-turbo 2JZ-GTE street builds.

Not sure whether you need a twin at all? Our comparison of twin disc and single disc clutches lays out where single-disc headroom runs out.

Signs your 2JZ-T56 build has outgrown its clutch

• Tach climbs with no matching gain in speed during a boosted pull, usually first noticed in third or fourth.
• The clutch held until a tune, larger turbo or fuel change raised torque, then started slipping.
• A stiff single-disc plate holds but makes the pedal tiring in daily traffic.
• Smell of hot friction material after spirited driving, or a blued flywheel face at teardown.

Diagnose before you order

Many slip complaints are actually release-side problems: a hydraulic bearing set with too little clearance can hold the pressure plate partly open. Work through the checks in our clutch slip diagnosis guide first. If the clutch genuinely cannot hold the torque, decide on facing type. Choose this organic RST for street comfort; step to the ceramic RXT 6482207M if the car sees drag strip launches or power beyond the RST rating. Budgeting the whole job? Our manual vs automatic repair cost guide shows where the money goes.

Fitment

Built for a Toyota 2JZ crankshaft and a T56-family transmission with a 1-1/8 in. x 26-spline input shaft, using the included steel flywheel with a 115-tooth ring gear. It does not fit the stock Supra V160 or W58 gearbox. Swap adapters from different makers locate the bellhousing and pilot differently, so confirm with your adapter supplier that it accepts a McLeod twin on this flywheel. Count your input shaft splines before buying; a 24-spline unit needs a different disc hub. If you are unsure, send us the engine, gearbox and adapter you are running and we will check it against the part number. Other kits for this swap include the Spec Super Twin ST63PT.

Install notes

• What is in the box: two organic discs, floater, diaphragm pressure plate, billet steel flywheel and an alignment tool. The pilot bushing, release bearing and flywheel/pressure plate bolts are not included.
• Clean the crank flange and flywheel mating face, use new bolts with thread locker, and torque in a star pattern to the figures on McLeod's sheet.
• Center both discs with the supplied tool and check that the disc hubs face the direction marked on each disc.
• Set release bearing clearance carefully; GM-pattern T56 bellhousings commonly use a slip-on hydraulic bearing such as the McLeod 1400-22 bearing.
• Give the organic facings a gentle break-in before any boost launches, following our new clutch break-in steps.

What is the difference between the RST 6482207 and RXT 6482207M?

Both are twin-disc kits for the same 2JZ to T56 combination with a steel flywheel. The RST uses full-face organic discs for smooth street engagement and is rated around 800 hp; the RXT uses segmented ceramic discs for more holding power, rated up to about 1,100 hp, with a harsher bite.

Can I keep my stock Toyota flywheel?

Not with this part number. The 6482207 is sold with its own billet steel flywheel carrying a 115-tooth ring gear, and the clutch is matched to it.

Will it work with a 24-spline T56?

No. The discs in this kit are 1-1/8 in. x 26 spline. Count the input splines on your gearbox before ordering.

Do I need a new pilot bushing and release bearing?

Yes, plan on both. Neither is included, and the correct pilot and bearing depend on the adapter plate and bellhousing used in your swap.

How should I break in an organic twin disc?

Drive normally with easy starts and no full-boost launches for the first few hundred miles so the facings bed evenly against the flywheel, floater and pressure plate.
