QA1 Adjustable Rear Frame Support for Select 1968-1972 GM A-Body (5284)

Fits select 1968-1972 Buick, Chevrolet, GMC, Oldsmobile, and Pontiac A-Body vehicles including Chevelle, GTO, and Cutlass.

QA1 Adjustable Rear Frame Supports are engineered to improve handling and traction by eliminating unwanted chassis flex. These braces reinforce the upper and lower trailing arm mounts, stabilizing the rear suspension geometry to prevent deflection during hard launches or heavy cornering. By tying these critical mounting points together, the chassis remains rigid, allowing the suspension to work more efficiently.

Constructed from high-strength 1-inch diameter cold rolled steel tubing, these supports are built for durability and performance. They feature zinc-plated adjustable threaded sleeves that allow you to set the proper preload in the rear trailing arm mounts after installation. The design is carefully profiled to clear both stock and aftermarket mufflers, providing a bolt-on solution that does not require exhaust modification.
