It utilizes our reinforced Steel Backed Copper Kevlar Organic friction material, coupled with a single diaphragm heavy-duty pressure plate with increased clamping force to give you smooth and reliable engagement and higher torque holding capacity. The pedal feel will be heavier than our Stage 1 (1OS) clutch kit by approximately 20%. At Action Clutch, safety is our top priority. We understand how catastrophic engine or transmission damage can be caused by springs popping out which is why we use our patented, fully enclosed spring retainers to keep your investment protected at all times. Every kit is quality checked by one of our experienced engineers (with over 60 years of collective experience) and signed off as safe before being released as a finished product. This gives you peace of mind knowing that your Action Clutch will perform consistently every time. 100% INCREASED HOLDING CAPACITY OVER FACTORY KIT RECOMMENDED FOR HEAVY-DUTY STREET USE AND MILD TRACK-USE\nStage 1 HD Clutch Kit (2OS) for Subaru WRX STI 2004-2021 2.5L DOHC (EJ257) Turbo AWD\n\u003cp\u003eThe Action Clutch ACR-1802-2OS Stage 1 HD clutch kit is engineered for 2004-2021 Subaru WRX STI models equipped with the 2.5L DOHC EJ257 turbocharged engine and all-wheel drive. Designed for stock vehicles and basic bolt-on applications, this kit provides dependable engagement, increased torque capacity, and consistent performance for demanding street driving and mild track use. It delivers approximately 100% greater holding capacity than the factory clutch kit while maintaining smooth, predictable operation.\u003cbr\u003eThe kit uses reinforced steel-backed copper Kevlar organic friction material paired with a single-diaphragm heavy-duty pressure plate.
