ACT Heavy Duty Performance Street Sprung Clutch Kit for 2012-2018 Jeep Wrangler JK (JP4-HDSS)

Fits 2012-2018 Jeep Wrangler and Wrangler JK models including Rubicon, Sahara, Sport, and Unlimited trims.

The ACT JP4-HDSS Heavy Duty Performance Street Clutch Kit is engineered to provide increased torque capacity and durability for Jeep Wrangler JK owners who demand more from their drivetrain. This kit combines ACT’s Heavy Duty pressure plate with a Performance Street sprung-hub disc, offering a smooth pedal feel and quiet operation while maintaining the strength needed for spirited street driving and rugged off-road use.

The pressure plate features a proprietary diaphragm design that significantly increases clamp load while reducing deflection. Each diaphragm undergoes a rigorous four-stage heat-treating process to ensure consistent performance over its lifespan. The Performance Street disc utilizes premium organic friction materials that are steel-backed for higher burst strength and improved heat dissipation.
