The ACT JP4-HDSS kit pairs ACT's highly regarded Off-Road Heavy Duty pressure plate with ACT's most popular Performance Street disc, built for Jeep Wrangler owners running larger tires, added weight, and off-road use who need more clamping force and torque capacity than stock. ACT Heavy Duty pressure plates use an exclusive diaphragm design to increase clamp load and reduce deflection, and every diaphragm goes through a four-stage heat-treating process for consistent, long-lasting performance. The included Performance Street disc uses premium organic friction material with high copper content for better heat transfer, plus a steel-backed lining for greater burst strength and durability, giving smooth street-friendly engagement with a meaningful increase in torque capacity over stock.
