More Info:
Drawing on an extensive, race-winning heritage, Quarter Master designed the all new 7.25″ Mitsubishi Evo Race Clutch to perform well in a broad range of racing platforms. The new clutch utilizes eight integral steel hardened legs to provide a much longer lifespan than one-piece aluminum covers where the floater and pressure plates have a tendency to wear into the drive legs. The 8-leg design also reduces stress on drive legs by 25 percent and creates a stiffer cover and smoother range on the diaphragm spring motion. A lower moment of inertia and gear drive friction design allow for quicker, smoother shifts. In addition, the gear drive clutch hub is located on the friction pack to enable easier transmission installation, much smoother and quicker shifting, improved input shaft wear and increased hub strength.
- Integral steel leg design prevents floater and pressure plate wear into the drive legs & reduces stress by 25%
- Rebuildable design ensures an extra long service life
- Gear drive clutch hub is located on the friction pack to enable easier transmission installation, smoother & quicker shifting & improved input shaft
- Lower moment of inertia & gear drive friction design allow for quicker, smoother shifts
- 2-Disc design is great for use in drag racing, drifting & road racing Evo applications up to 900 FT/LBS.
