Clutch Masters FX400 6-Puck Clutch Kit

2018-2024 WRX

Clutchmasters Short Shift (or SS) series of billet aluminum clutch covers were designed to take a typical single disc clutch kit to that next level of performance. The goal of their engineers was to develop a clutch kit that was street friendly, allowed for faster shifts, lighter rotating mass, and the consistent pedal feel you expect from a clutch on the track. To accomplish this they took everything learned from decades of perfecting their Twin Disc clutch kits and designed it around the fitment of an OE style clutch cover. 

Features of Short Shift Billet Clutch Kits:

• Shorter, faster, more precise shifts
• 10% lighter then OE stamped steel cover
• Fits stock single disc flywheel (or any aftermarket single disc flywheel designed for OE style clutch kits)
• Heavier diaphragm allows more clamping force to be obtained
• Modified pivot point on steel pressure plate casting makes pedal feel minimally heavier then a stock clutch. 
• Works with factory hydraulics (For best results we recommend our internal hydraulic release bearing and master cylinder upgrades)
• Comes with new throw out bearing specifically designed to take advantage of the short throw of the clutch

The FX400 System uses the Power Plus I, Hi-Levarage, Heavy-Duty Pressure Plate with a custom and extremely durable, Sprung Ceramic disc. This is the ultimate extreme duty street and/or road/drag racing system. It is available in a 6 or 8 ceramic puck configuration. The 6-puck being the more aggressive setup and 8-puck being the less aggressive. The sprung hub design allows for moderate dampening in high-torque applications, rendering it much more street friendly than solid or rigid designs. This disc is designed for long life, outstanding holding capacity, and rapid heat dissipation.

The FX400/HDC6 (6-Puck) ceramic paddle design creates a quick and rapid engagement as well as clutch chatter that may not be ideal for street driven vehicles. *Warning* Due to the solid (no Marcel) friction rivet design, the FX400 6 disc engages very quickly and may chatter slightly in first and reverse. To help alleviate this problem, we only use premium ceramic friction material.

-Organic/ Kevlar/ Fiber-Tough Clutch kits are expected and tend to have a higher life expectancy than OEM, however not guaranteed. Improper Installation, Driving style, performance upgrades, Break in procedure and light weight flywheels will effect and have a role in determining the life expectancy of the clutch kit.
