Description

Overview

Driving the alternator consistently prevents battery drain and drops in cab electronics bus voltage. Ribbed construction grips the crankshaft and alternator pulleys tightly, transferring drive power through sudden engine throttle changes without squealing or glazing. The compound holds up against oil mist, belt dust, and under-hood temperature spikes without stretching out prematurely.

Features

Resists glazing, heat cracking, and oil contamination
Ribbed design minimizes slippage under heavy electrical loads
Dampens cyclic vibration from the crank pulley

Applications

Runs across the engine crankshaft and alternator drive pulleys on the front accessory drive.
