HEAVY DUTY CLUTCHES

Illinois Auto Truck offers 4 different styles of NEW 14″ & 15″ heavy duty clutches. All four models are interchangeable and can be used in various applications. Our range covers torque capacities up to 3000 foot pounds. Clutch Discs are available with organic, ceramic, or kevlar facings.
Easy Effort

Easy Effort clutches utilize coil-spring technology. The assist springs serve to lower the bearing load, and therefore, reduce pedal effort. Adjustment is achieved through a Spring-A-Just mechanism.

AutoSet Clutch

The patented AutoSet Clutch improves on all previously available versions of self-adjusting heavy-duty clutches. This design incorporates a dual cam spring feature to provide a strong and balanced adjustment. The over-adjustment protection feature will hold the adjustment in place should shock to the truck occur.

Angle Spring

The original clutch design incorporates 6 coil-spring, pressure springs, to allow for a smooth engagement throughout the clutch life.
