Spring Engagements

Built for high performance, the Comet 4PRO and 108EXP mean business. These clutches are heavy duty and durable, yet quiet and smooth. Engagement can be set from 2500 to 5000 rpm. Calibration and actuation is achieved through swing arm design. The pulley diameter is 8 inches and bores and offsets are sized to fit most sleds from the 1970s to the present. Rugged from the inside out, the housings are die-cast aluminum. Also, a new moveable sheave bushing with high resistance material extends clutch performance and life.

Which 102C and 108EXP Clutch Should You Choose?
