Overview

The ACT Heavy Duty Race Sprung 4 Pad Clutch Kit is engineered for Subaru enthusiasts seeking a robust and reliable clutch solution capable of handling high horsepower street and race applications.

ACT’s design philosophy centers on maximizing clamp load and clutch life through an exclusive diaphragm pressure plate that undergoes a rigorous four-stage heat treatment process. The precision cover stamping adds rigidity and consistency, while the 4-pad spring-centered race disc incorporates advanced spring retainers to dampen torsional vibrations and resist failure under demanding conditions. This engineering approach ensures smooth operation at high RPMs and reliable performance even in harsh environments.

For Subaru owners, this clutch kit offers a significant upgrade over OEM components, boasting an 86% increase in torque capacity to 574 ft/lbs. The ceramic friction material provides high heat tolerance, making it well-suited for aggressive street driving and occasional track sessions. While engagement is firmer and pedal effort light to moderate, the faster shifting response enhances driving precision and control, essential for performance-oriented Subaru platforms.
