Product Description: HD-M/Race Rigid 4 Pad Clutch Kit

The HD-M/Race Rigid 4 Pad Clutch Kit by ACT is a meticulously engineered solution designed to elevate performance in race applications. Weighing 15.2 lbs., this kit boasts a torque capacity of 510 ft/lbs., marking an 81% increase over OE capacity, ensuring enhanced power transmission and durability.

Crafted with a ceramic disc material, this kit features a clutch disc diameter of 9.4 inches (240 millimeters) and a robust input shaft diameter of 1 inch, optimizing torque transfer and reliability under demanding conditions. The heavy-duty pressure plate, renowned for its exclusive diaphragm design, effectively boosts clamp load, minimizes deflection, and prolongs clutch life.

The heart of this kit lies in its 4-pad rigid race discs, meticulously manufactured with high-quality ceramic friction materials. The chrome-moly hub, heat-treated for strength and resilience, facilitates swift and precise gear shifts, enhancing overall performance. While engagement may be harsher, the lightweight, rigid design guarantees trouble-free service, particularly well-suited for smaller engine applications.

The inclusion of ACT's patented Monoloc ensures seamless compatibility and optimal performance, replacing conventional two-piece collars with a single, hardened chrome-moly steel construction. This upgrade provides uniform loading on the bearing and pressure plate, maintaining proper alignment irrespective of driving conditions or vehicle modifications.

Key Features:

  • Feel: Light to moderate pedal effort, aggressive engagement, increased gear rattle, confidence during hard shifts
  • Life: Moderate friction life, extended by ACT's exclusive diaphragm design, with a notable improvement in release mechanism life; however, rigid design may lead to increased spline wear
  • Quality: Carefully engineered, precisely assembled, and accurately balanced, utilizing select ceramic friction materials for high heat tolerance and maximum performance, with a significant enhancement in the release mechanism
  • Recommended Use: Primarily recommended for race applications

Nice material, holds collar shape well.
Color: Wine Red, Navy Blue, Black, Size: Medium
Good value for the money. You can machine wash and dry on low heat, in my opinion. Laying flat is too much of a pain.
