This bushing cushions the connection between the torsion bar spring plate and the chassis. It absorbs road vibrations and reduces metal-to-metal contact, helping maintain smooth suspension movement and ride comfort while preserving alignment.

Function
•  Cushions and supports the rear spring plate at the torsion housing
•  Absorbs vibration and road shock
•  Maintains correct suspension alignment and geometry
•  Prevents metal-to-metal contact within the suspension system
•  Allows controlled torsion bar movement

Over time, rubber bushings degrade due to age, heat, and exposure to the elements. Worn bushings can cause excessive play, poor alignment, and increased vibration, negatively affecting ride quality and handling. Replacing them restores proper suspension function, improves comfort, and protects surrounding components.

When to replace
•  Visible cracking, splitting, or hardening of rubber
•  Excessive rear suspension play or noise
•  Uneven ride height or alignment issues
•  During suspension rebuild or restoration
•  Signs of deterioration due to age or contamination
