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
  • Aluminum Flywheel - Reduces rotational mass for quicker throttle response
  • 6-Bolt Crankshaft Pattern - 168-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

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 includes a dedicated flywheel matched to this clutch and does not use the factory flywheel.

What warranty applies to this clutch kit

Contact McLeod Racing directly for current warranty terms and coverage on this clutch kit.

  4. Install the floater plate and pressure plate, aligning the drive straps as specified in McLeod's installation instructions
  5. Tighten the pressure plate nuts in a star pattern to McLeod's specified torque values
  6. Reinstall the transmission, throwout bearing, and bellhousing
