ACT Heavy Duty Race Sprung 4 Pad Clutch Kit 2002-2005 WRX

DESCRIPTION

The ACT Heavy Duty Race Sprung 4 Pad Clutch Kit for the 2002–2005 Subaru WRX is built for high-horsepower street cars and race applications requiring strong torque capacity and fast shifting. The SB9-HDG4 kit pairs ACT’s proven Heavy Duty pressure plate with a sprung 4-pad ceramic race disc, delivering increased clamp load, reduced deflection, and long-term durability through ACT’s exclusive four-stage heat-treating process.

The spring-centered 4-pad race disc helps damp torsional vibrations for improved drivability while maintaining aggressive engagement and quick shift response. Reinforced spring retainers with wraparound windows increase strength under load, while ACT’s patented Monoloc release mechanism provides improved alignment, uniform bearing load, and extended release mechanism life.

WHY?

This clutch kit is ideal for WRX owners pushing serious power who still want a manageable pedal feel. It delivers light to moderate pedal effort with aggressive engagement and confident shifting under load. With a 555 ft-lb torque capacity and ACT’s Heavy Duty pressure plate, this kit offers a strong balance of street usability and race-ready performance.

• Heavy Duty pressure plate with increased clamp load
