Clutch Masters FX400 Sprung Clutch Kit (Must Use w/ Single Mass Flywheel) Honda Civic Si 2017-2020 | 08150-HDCL-D

Upgrade to the next level of performance with the Clutch Masters FX400 8-Puck Clutch Kit, engineered for enthusiasts who demand serious holding power with improved street usability compared to full race clutches. Designed as a race/street hybrid, the FX400 is ideal for high-horsepower builds, aggressive driving, and weekend track use.

Product Overview (SEO Optimized)

The FX400 system features a Power Plus I high-leverage pressure plate paired with a sprung 8-puck ceramic disc, delivering approximately 170% increased holding capacity over stock. This setup provides rapid engagement, excellent heat resistance, and improved durability, while still maintaining a level of drivability suitable for experienced street drivers.

Unlike rigid race clutches, the sprung hub design helps absorb drivetrain shock, making the 8-puck configuration more manageable than more aggressive 6-puck or solid hub setups.
