Heavy Duty – AMT & SOFT PEDAL®

SOFT PEDAL® clutches have state-of-the-art diaphragm spring technology resulting in
smoother engagement. Our SOFT PEDAL® clutches incorporate the still popular manual
adjustment feature. The drive strap design provides a smoother transfer of energy and
avoids the internal friction that causes metal wear.

Improved heat dissipation is achieved through enlarged cover ventilation. The special
diaphragm design reduces pedal effort by 30%, thereby reducing driver fatigue.
