McLeod 6306807MD Modular RST HD Twin Disc Clutch Kit

The McLeod 6306807MD Modular RST HD Twin Disc Clutch Kit is engineered for high-horsepower street and street/strip performance enthusiasts who need more holding power than a stock clutch while preserving excellent everyday drivability. Positioned between McLeod's RST and RXT twin-disc systems, the RST HD delivers a refined balance of torque capacity and driver-friendly street manners.

At the heart of this kit is a hybrid twin-disc design that pairs a full-face organic friction disc for smooth, progressive engagement with a segmented ceramic friction disc for increased bite and superior torque holding under aggressive driving conditions. The diaphragm-style pressure plate and Blanchard-ground floater plate with multiple retention straps contribute to quiet, consistent operation and excellent release characteristics.

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