The HiT clutch from Dr. Pulley's PRO SERIES rounds out the top of of the crop of clutches. The innovative HiT clutch uses motor torque - not just centrifugal force alone - a combination that puts this product in the upper end of power performance clutch systems. Made of two interlocked movable parts, it's originality is due to using a cleverly devised sliding/wedge system to create additional pressure that combines both torque and centrifugal energy - as opposed to the average clutch system which relies on centrifugal force alone. The stronger the motor (higher resistance for your motor to work with), means more pressure for the sliding/wedge to exert on the surface of the clutch shoes, which means saving performance energy that would otherwise be lost.
Other clutches start to slip when they reach certain rpm's or speeds. Not with the HiT clutch! Daily drivers get a new edge when going uphill or overtaking. Sport pilots appreciate increased power performance in higher rpm's.
