Clutch Masters FX400 6 Puck Single Disc Clutch Kit 06-14 WRX / 07-12 Legacy | 170% Holding Capacity Increase | High-Performance Clutch Kit
Overview
The Clutch Masters FX400 6 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 and road or drag racing applications, this clutch kit is ideal for enthusiasts seeking aggressive engagement and reliable torque management in high-performance driving scenarios. The 6-puck configuration offers a more aggressive setup compared to the 8-puck option, providing rapid engagement and enhanced power transfer.
Built around the Power Plus I heavy-duty pressure plate and a custom sprung ceramic disc, the FX400 system balances durability with street usability. The sprung hub design provides moderate dampening to reduce drivetrain shock and improve drivability compared to solid hub designs. Clutch Masters’ use of premium ceramic friction material ensures excellent heat dissipation and long-lasting performance under demanding conditions, making this clutch a standout choice for Subaru owners pushing their vehicles beyond stock limits.
For Subaru WRX and Legacy owners, this clutch kit translates to improved throttle response, reduced clutch slip, and the ability to handle significant power upgrades without sacrificing street drivability. While the 6-puck design may introduce some clutch chatter during first gear and reverse engagements, it offers a direct and immediate connection favored by racers and aggressive drivers. This clutch is best suited for modified vehicles where increased holding capacity and durability are paramount.
