McLeod 6406807MD RST HD Twin Disc Clutch Kit with Steel Flywheel

The McLeod 6406807MD RST HD Twin Disc Clutch Kit is engineered for high-horsepower enthusiasts who demand serious torque capacity while retaining excellent street manners. Positioned between McLeod's RST and RXT twin-disc systems, the RST HD delivers an ideal balance of drivability and all-out performance for drivers who push their vehicles hard on the street and at the track.

At the heart of this kit is a hybrid twin-disc design combining a full-face organic friction disc for smooth, predictable engagement with a segmented ceramic friction disc for increased bite and superior torque holding capacity under aggressive driving conditions. The diaphragm-style pressure plate contributes to a lighter-than-stock pedal feel, keeping the kit streetable even at elevated power levels.

Key Features:

• Dual-disc (twin disc) clutch system rated for high-horsepower GM 6.2L applications
• Hybrid organic and ceramic friction disc materials for street/strip versatility
• Diaphragm-style pressure plate with lighter-than-stock pedal effort
• 9.688 in. (246mm) disc outer diameter
• 1-1/8 in. x 26-spline input shaft compatibility
• Billet steel flywheel included
• Blanchard-ground floater plate with drive straps to reduce noise and chatter
• CNC-machined adapter ring — no dedicated flywheel required in most applications
• Alignment/pilot tool included for precise installation
• Throwout bearing and pilot bushing not included

Kit Includes: Diaphragm pressure plate, two friction discs (organic + ceramic), billet steel flywheel, floater plate, adapter ring, and pilot alignment tool.

All McLeod street performance clutches require a break-in period of 500–750 miles of street stop-and-go driving before wide-open-throttle use, allowing the discs to properly seat against the pressure plate and flywheel. Sold as a complete kit.
