McLeod 6435803MD RST Street Twin Disc Clutch Kit 800HP Metallic 10-Spline

The McLeod 6435803MD RST Street Twin Disc Clutch Kit is the metallic-disc variant of McLeod's popular RST Street Twin power pack, engineered for high-horsepower street performance applications. Rated to handle up to 800 horsepower, this twin-disc system delivers serious torque capacity while remaining fully street-drivable.

At the heart of this kit are two full-face metallic friction discs paired with an unsprung hub design, offering increased torque bite and durability compared to the standard organic-faced RST — making it an ideal step up for more aggressive street and occasional strip use. A diaphragm-style pressure plate ensures consistent clamping force and predictable engagement.

McLeod Racing's RST Street Twin line is designed to be an economically priced high-performance clutch solution.
