Equalizer Bushing 321-221 – Vibration Dampening Bushing for Hutch Suspensions

The Equalizer Bushing 321-221 is a robust suspension component engineered for use in heavy-duty Hutch suspension systems. Designed to maintain axle alignment and allow smooth pivoting of the equalizer beam, this bushing plays a vital role in absorbing shock and vibration across tandem axle configurations—improving ride quality and extending suspension life.

Much like a joint that cushions two moving parts, this bushing ensures seamless suspension articulation under load, helping prevent uneven tire wear and structural fatigue over time.
