Stage 1 HD Clutch Kit (2OS) for Subaru WRX STI 2004-2021 2.5L DOHC (EJ257) Turbo AWD Includes ACT Monoloc

Action Clutch’s Stage 1 HD (2OS) Kit has been designed for vehicles ranging from stock to basic bolt-on cars. 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.
