Clutch Masters FX400 8 Puck Single Disc Clutch Kit 06-14 WRX / 07-12 Legacy | 170% Holding Capacity | High-Duty Street & Race Clutch Kit
Overview
The Clutch Masters FX400 8 Puck Single Disc Clutch Kit is engineered for Subaru WRX (2006-2014) and Legacy (2007-2012) models, delivering a substantial 170% increase in holding capacity over stock clutches. Designed for extreme duty street use and road or drag racing, this clutch system balances aggressive performance with street-friendly operation. It features a heavy-duty sprung ceramic disc that provides rapid engagement and excellent heat dissipation, making it ideal for enthusiasts who demand reliable power transfer without sacrificing drivability.
Built around the Power Plus I heavy-duty pressure plate, the FX400 kit incorporates premium ceramic friction material and a sprung hub design to moderate driveline shock and reduce chatter compared to solid disc setups. The 8-puck configuration offers a less aggressive engagement than the 6-puck variant, making it better suited for street-driven vehicles that still require robust torque capacity. Clutch Masters’ engineering focuses on durability and consistent performance, ensuring the clutch withstands the rigors of high-torque applications while maintaining smooth operation.
For Subaru owners upgrading their drivetrain for increased power or motorsport use, this clutch kit provides a significant improvement in holding strength and heat management. The sprung hub design helps absorb drivetrain vibrations, enhancing street comfort and reducing premature wear. While ceramic discs are not intended to extend clutch life, they improve durability under demanding conditions, making the FX400 an excellent choice for WRX and Legacy drivers pushing their vehicles beyond stock limits.
