UMI Performance Polyurethane Rear End Housing Replacement Bushings for Select 1965-1997 GM (3000-B)

Fits select 1965-1997 Buick, Chevrolet, GMC, Oldsmobile, and Pontiac models.

UMI Performance 3000-B polyurethane bushings are designed to replace the compliant factory rubber rear end housing bushings. Over time, original equipment rubber is susceptible to dry rot, cracking, and hardening due to environmental exposure and mechanical stress, which compromises suspension geometry and ride quality. These high-durometer polyurethane replacements restore precision to your rear suspension by securing the upper control arm mounting points on the differential housing.

Specifically engineered for the "ears" of the rear end housing, this kit includes two bushings and two polyurethane washers. The included washers are critical for preventing the bushings from walking side-to-side during lateral loading, ensuring consistent axle centering whether on the street or the track. These are a direct-fit upgrade for vehicles retaining factory-style mounting points.
