Construction & Design:

ACT’s Heavy Duty Street Mass HD-O / Race Sprung 6-Pad Clutch Kit is crafted using premium materials and advanced manufacturing techniques. The pressure plate features a unique diaphragm spring design that increases clamp load while minimizing deflection, which not only improves clutch engagement but also extends the overall lifespan of the clutch assembly. The diaphragm springs undergo a rigorous four-stage heat treatment process to ensure maximum strength and resistance to heat-induced fatigue.

The 6-pad race disc incorporates high-quality ceramic friction materials that maintain consistent grip even under high temperatures and abusive driving conditions. Its spring-centered design effectively absorbs driveline shock, reducing stress on transmission components and improving drivability. Precision machining and balancing of all components guarantee smooth operation and reliability at high engine speeds.

Performance & Sound

This clutch kit delivers aggressive engagement with light to moderate pedal effort, providing drivers with precise control and confidence during hard shifts. The ceramic friction material and robust construction allow it to hold high torque loads without slipping, making it well-suited for off-road racing and spirited street driving. While the clutch produces OE to mild gear rattle, this characteristic is typical of performance-oriented clutches and contributes to the overall tactile feedback and engagement feel.
