ACT HA3-SPR4 Sport/Race Rigid 4 Pad Kit

The ACT HA3-SPR4 Sport/Race Rigid 4 Pad Kit is engineered for those seeking a significant upgrade in clutch performance. This kit incorporates a Sport pressure plate designed with an exclusive diaphragm configuration that enhances clamp load while minimizing deflection, ultimately extending clutch life. Each diaphragm undergoes a rigorous four-stage heat treatment to ensure consistent, high-performance results.

Key Features

• Light to moderate pedal effort with aggressive engagement, leading to increased gear rattle.
• Moderate friction life, optimized by ACT's unique diaphragm design. Note that the rigid construction may lead to increased spline wear.
• Constructed with select ceramic friction materials, offering high heat tolerance and maximum performance.
• Designed specifically for race applications.
• Each unit is 100% clamp load tested and dynamically balanced for reliable operation at high RPMs.
