Dorman 533-420 Suspension Control Arm Bushing Kit

Dorman 533-420 is a suspension control arm bushing kit built for specific rear upper and rear lower applications on classic GM vehicles. It is precision-engineered and tested to provide a direct replacement for the original equipment bushing on supported Buick, Chevrolet, Oldsmobile, and Pontiac models.

Key Features

  • OE-style suspension control arm bushing kit for rear suspension service
  • Rubber and steel construction for controlled movement and structural support
  • Standard replacement grade for direct-fit repair work
  • Black and silver finish
  • Designed for rear upper and rear lower control arm positions
  • Cross-references MOOG Chassis Products K5161 and Mevotech Supreme MK5161 for the same application

Detailed Description

This Dorman suspension control arm bushing kit, part number 533-420, is made for restoring worn rear suspension pivot points on a wide range of 1964-1977 GM cars. It is a practical choice for Buick Century, Regal, Skylark, LeSabre, Riviera, Chevrolet El Camino, Malibu, Monte Carlo, Oldsmobile Cutlass, Cutlass Supreme, Delta 88, 98, Starfire, and Pontiac GTO, Grand Prix, LeMans, Tempest, Catalina, Bonneville, Grand Am, and Grand LeMans applications. The rubber-and-steel design helps maintain control arm alignment and suspension articulation while replacing deteriorated original bushings.

What It Helps Fix

  • Rear suspension looseness or excess play
  • Clunking or squeaking from worn control arm bushings
  • Uneven tire wear caused by unstable rear suspension geometry
  • Handling drift or reduced rear-end stability
  • Visible cracking, separation, or deterioration in original bushings

Installation Notes and Tips

Verify the control arm position before ordering, since this part is used in both rear upper and rear lower locations depending on the vehicle. Confirm the vehicle year, make, model, and suspension position against the fitment list for Buick, Chevrolet, Oldsmobile, and Pontiac applications. Inspect the control arm and surrounding hardware for wear before installation, and replace any damaged mounting components as needed. Professional suspension service and proper alignment checks are recommended after repair.

Quality Assurance

Dorman states that this bushing kit is precision-engineered and rigorously tested to serve as a reliable replacement for the original equipment on specific vehicles. Part number 533-420 is built as a standard replacement solution for restoring factory-style suspension performance.
