- Anti-swell, alloy-impregnated heavy-duty cork-based facings for smooth clutch take-up
- Allow modulation, unlike paper clutches that tend to snatch
- Complete engine set of friction plates, HD springs and steel separator plates prevent premature driven plate wear, oil muddying and loss of stack height
- Built with swagged aluminum carriers that spread the load on the clutch basket and prevent clutch basket "dogging"
- 10-15% uprated heavy duty clutch springs
