Product Description

The QA1 5285 Adjustable Rear Frame Braces are engineered to eliminate unwanted chassis flex at the rear trailing arm mounts on 1978-1988 GM A-Body and G-Body vehicles including the Monte Carlo, Malibu, El Camino, Buick Regal, Cutlass Supreme, and Pontiac Grand Prix. Factory trailing arm mounts on these platforms are prone to deflecting under hard acceleration and cornering, leading to inconsistent handling, wheel hop, and degraded traction. QA1's tubular steel braces tie and reinforce the upper and lower trailing arm mounting points, dramatically reducing this flex for more predictable rear suspension behavior.

Built from 1-inch diameter cold rolled steel tubing and featuring zinc plated adjustable threaded sleeves, these braces allow on-car preload adjustment of the rear trailing arm mount after installation - providing tuning flexibility without removal. The design is thoughtfully engineered to clear both stock and aftermarket mufflers, making installation clean and straightforward. All necessary hardware is included. Proudly made in Lakeville, Minnesota, the QA1 5285 is a key component in any G-Body or A-Body handling upgrade and is included in QA1's Level 2 Handling Kit for these platforms.
