McLeod 6306607MD RST HD Twin Disc Clutch Kit with Aluminum Flywheel

The McLeod RST HD Twin Disc Clutch Kit (6306607MD) is a high-performance twin-disc clutch system engineered for enthusiasts who demand significantly greater holding power than a stock clutch while preserving everyday street driveability. Positioned between McLeod's RST and RXT twin-disc lines, the RST HD strikes an ideal balance of performance and drivability for spirited street driving and weekend track use.

At the heart of this kit is a hybrid dual-disc design that pairs a full-face organic friction disc for smooth, predictable engagement with a segmented ceramic friction disc for increased bite and elevated torque capacity under aggressive driving conditions. This combination delivers a lighter-than-stock pedal feel without sacrificing holding power.

Key Features:

• Hybrid twin-disc system with organic and segmented ceramic friction materials
• Rated to handle up to 950 horsepower
• 9.688-inch (246mm) diameter clutch discs
• 1-1/8-inch diameter, 26-spline input shaft compatibility
• Diaphragm-style pressure plate for consistent clamping force
• Sprung hub disc design for improved NVH and drivability
• Low rotating mass for quicker engine response and rev matching
• Billet aluminum flywheel included (168-tooth ring gear)
• Alignment tool included for proper installation
• Blanchard ground floater plate with multiple straps to reduce noise

Kit Includes:

• Diaphragm pressure plate
• Two friction discs (one organic full-face, one segmented ceramic)

Break-In Requirement: All McLeod street performance clutches require a break-in period of 500–750 miles of normal street, stop-and-go driving before wide-open-throttle use. This allows the discs to properly seat against the pressure plate and flywheel for maximum performance and longevity.
