McLeod Racing RST HD Twin Disc Clutch Kit
The McLeod RST HD Clutch Kit is engineered for performance enthusiasts who demand more holding power than stock while maintaining excellent street manners. Positioned between McLeod's RST and RXT twin-disc systems, the RST HD delivers an ideal balance of drivability and performance for a more spirited driving style.
Key Features
- Hybrid Twin-Disc Design - One side of each disc uses full-face organic friction material for smooth engagement, the other uses segmented ceramic friction material for increased bite and holding power
- Up to 950 Horsepower Rating - Built to withstand aggressive driving conditions while preserving street-friendly characteristics
- N/A Crankshaft Pattern - N/A, adapter ring-tooth ring gear for precise fitment and engagement
- 1-1/8 inch, 26 spline Input Shaft - Matches the transmission input shaft specification for correct fitment
This adapter ring version bolts to an existing compatible small-diameter flywheel and does not include a flywheel.
Fitment
Universal application. Fits vehicles equipped with a compatible small-diameter flywheel pattern (Chevrolet 153T, Chrysler 130T, Ford 157T, Buick/Oldsmobile/Pontiac 153T/156T) and a 1-1/8 inch, 26-spline transmission input shaft. Verify your specific flywheel pattern before ordering.

FAQ
What horsepower can this clutch kit handle
This RST HD twin-disc clutch kit is rated to support up to 950 horsepower.
Does this clutch require a specific transmission
This kit is designed for the specific input shaft spline and crankshaft pattern listed in the specifications. Verify your transmission's input shaft spline count and diameter before ordering.
What is the difference between the organic and ceramic disc sides
Each disc uses full-face organic friction material on one side for smooth street engagement and segmented ceramic friction material on the other side for increased holding power under hard use.
Is a throwout bearing or pilot bushing included
No. The throwout bearing and pilot bushing are not included and must be purchased separately if needed.
Does this clutch require a break-in period
Yes. McLeod recommends 500 to 750 stop-and-go miles or approximately 1,500 clutch cycles of normal street driving before driving aggressively. Do not break in this clutch on a chassis dyno.
Can I adjust the clamp load or pedal feel after installation
The pressure plate is manufactured to a fixed clamp load specification. Pedal feel is determined by the diaphragm pressure plate design and cannot be field adjusted.
Will this clutch work with my factory flywheel
This kit uses an adapter ring version designed to bolt to a compatible existing flywheel rather than the factory unit. Confirm your flywheel pattern matches before ordering.
What warranty applies to this clutch kit
Contact McLeod Racing directly for current warranty terms and coverage on this clutch kit.
Installation Instructions
- Remove the transmission and existing clutch assembly per the vehicle's factory service manual

- Install the floater plate and pressure plate, aligning the drive straps as specified in McLeod's installation instructions
- Tighten the pressure plate nuts in a star pattern to McLeod's specified torque values
- Reinstall the transmission, throwout bearing, and bellhousing
- Adjust clutch pedal free play per the factory service manual specification
- Follow McLeod's recommended break-in period of 500 to 750 stop-and-go miles before aggressive driving
