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 Evo X 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.
