Clutch Masters FX500 6 Puck Single Disc Clutch Kit 03–06 Baja / 13–17 Crosstrek / 97–12 Forester / 94–21 Impreza / 90–14 Legacy | 200-400% Increased Holding Capacity | Race-Only Clutch Kit
Overview
The Clutch Masters FX500 6 Puck Single Disc Clutch Kit is a race-focused upgrade designed for Subaru models including the Baja (2003–2006), Crosstrek (2013–2017), Forester (1997–2012), Impreza (1994–2021), and Legacy (1990–2014). This kit delivers a substantial increase in holding capacity—between 200% and 400% over stock—making it ideal for motorsport applications and high-performance builds where clutch slip is unacceptable. It is not intended for street use due to its aggressive engagement characteristics and heavy pedal effort.
Engineered with a Power Plus II Pressure Plate and a solid 6-puck ceramic button disc, the FX500 system emphasizes rapid heat dissipation and exceptional clamping force. The design incorporates precision heat-treated diaphragms and heavy-duty straps to ensure durability under extreme conditions. Clutch Masters’ commitment to quality and performance is evident in the meticulous construction and materials chosen for this kit, making it a trusted choice among Subaru racing enthusiasts.
For Subaru owners pushing their vehicles to the limit, this clutch kit offers immediate engagement and a high level of control, essential for drag racing, track days, and other competitive environments. While the ceramic puck design produces clutch chatter and a heavy pedal feel, these traits are a trade-off for the clutch’s ability to handle extreme torque loads and heat without fading. This kit is a purpose-built solution for those who demand uncompromising performance from their Subaru drivetrain.
