Upgrade your 2018-2021 Subaru WRX with the Action Clutch Stage 1 HD (2OS) Clutch Kit, part number ACR-1816-2OS-FW. Designed for stock vehicles and basic bolt-on builds, this kit combines a reinforced steel-backed copper Kevlar organic friction disc with a single-diaphragm heavy-duty pressure plate. The result is smooth, reliable engagement with increased torque-holding capacity for demanding street driving and mild track use.
Compared with the Action Clutch Stage 1 (1OS) kit, the Stage 1 HD delivers approximately 20% more pedal effort while providing up to 100% increased holding capacity over the factory clutch. This balance makes it a practical choice for drivers seeking additional performance without sacrificing everyday drivability. The included lightweight flywheel helps reduce rotating mass and supports quicker engine response.
Action Clutch prioritizes safety and long-term durability through its patented, fully enclosed spring retainers. These retainers help prevent clutch springs from dislodging and protect the engine and transmission from related damage. Each kit is inspected and approved by an experienced Action Clutch engineer before release, providing dependable fitment and consistent performance. This complete kit is engineered for the 2018, 2019, 2020, and 2021 Subaru WRX equipped with the 2.0-liter DOHC FA20DIT turbocharged engine and all-wheel drive.
