Function

The rubber bushing serves several purposes:

• Protects trim system hardware from metal-to-metal wear

• Maintains proper alignment of trim cylinders and hoses

Because trim systems operate under high load and vibration, bushings help extend the life of surrounding components.

Fitment Tip:
