Why Fleet Managers Choose This Part?

1. Anti-Slip Surface: The groove walls are machined to precise angles to ensure maximum friction with the belt, preventing power loss during high-load operations in hot climates.

2. Structural Integrity: Made from high-strength iron to resist cracking under the constant tension of the heavy-duty drive belts.

3. Vibration Dampening: Its mass and precise machining help in stabilizing the rotational inertia of the crankshaft, extending the life of your engine's front oil seal
