Clutch Masters FX500 6 Puck Single Disc Clutch Kit 04-05 Baja / 04-05 Forester | 200-400% Increased Holding Capacity | Race-Only Clutch Kit
Overview
The Clutch Masters FX500 6 Puck Single Disc Clutch Kit is a race-focused clutch system designed for Subaru Baja and Forester models from 2004 to 2005. Engineered to deliver a substantial increase in holding capacity—ranging from 200% to 400% over stock—this clutch kit is built for serious motorsport applications where rapid engagement and extreme durability are paramount. It is not intended for street use due to its aggressive engagement characteristics and heavy pedal effort.
At the core of the FX500 system is the Power Plus II Pressure Plate paired with a solid hub 6-puck ceramic button disc. This combination emphasizes high clamping force and rapid heat dissipation, ensuring consistent performance under extreme conditions. The clutch’s design incorporates precision heat-treated diaphragms, heavy-duty straps, and a friction-reducing lubricant to minimize diaphragm binding, reflecting Clutch Masters’ commitment to engineering excellence and race-proven reliability.
For Subaru enthusiasts focused on competition or high-horsepower builds, the FX500 clutch kit offers a significant upgrade in holding power and thermal management. The solid hub design provides instant engagement and disengagement, which is critical for track and drag racing scenarios. While the ceramic puck design delivers quick pedal response and clutch chatter, it is essential to understand this clutch’s race-only intent to maximize its benefits without compromising drivability or component longevity on the street.
