Clutch Masters FX400 8 Puck Single Disc Clutch Kit 04-05 Baja / 04-05 Forester | 170% Holding Capacity Increase | High-Duty Clutch Kit
Overview
The Clutch Masters FX400 8 Puck Single Disc Clutch Kit is engineered for Subaru Baja and Forester models from 2004 to 2005, delivering a substantial 170% increase in holding capacity over stock clutches. Designed for both aggressive street driving and road or drag racing, this kit offers a balance of extreme durability and street-friendly engagement. It features a heavy-duty sprung ceramic disc that provides rapid heat dissipation and long-lasting performance under high torque loads.
Built around Clutch Masters’ Power Plus I heavy-duty pressure plate, the FX400 system utilizes premium ceramic friction material and a sprung hub design to moderate driveline vibrations and reduce clutch chatter. The 8-puck configuration offers a less aggressive engagement compared to the 6-puck variant, making it more suitable for street-driven vehicles that require strong holding power without sacrificing drivability.
For Subaru owners seeking a clutch upgrade that can handle increased power and torque while maintaining manageable engagement characteristics, this kit represents a reliable solution. Its design supports rapid engagement and durability, essential for performance applications where clutch slip and fade are concerns. However, it is important to note that ceramic-based discs are intended for high-performance use and may reduce clutch life if used in stock or near-stock vehicles due to their aggressive nature.
