QA1 78-88 GM G Body, 82-02 GM F Body Adjustable Lower Trailing Arms

Unwanted axle wrap and improper wheelbase positioning can hurt performance, causing wheel hop and fender rubbing with larger wheel and tire packages. The QA1 adjustable trailing arms address these concerns with an easy-to-install kit, providing tremendous value for your setup.

CENTER YOUR REAR WHEELS

Whether you have a 3rd or 4th Gen F-Body optimized for performance, or a G-Body with larger wheels, maintaining proper wheelbase is crucial for performance and tire clearance. QA1’s adjustable trailing arms help position your rear axle within the wheel well, accommodating larger rims without sacrificing performance. With up to an inch of adjustability, you can eliminate common rubbing issues and fine-tune your wheel's position.

REDUCE UNWANTED FLEX

Factory trailing arms with rubber bushings often flex, inducing wheel hop and degrading performance. QA1’s adjustable trailing arms feature robust tubular construction, a durable powder coat finish, greaseable polyurethane bushings, and chromoly rod ends for superior strength and longevity.

EASY BOLT-IN INSTALLATION AND ADJUSTABILITY

Every QA1 kit is designed for a hassle-free, fully bolt-in installation. The parts come powder-coated and include all necessary hardware. A double adjustable linkage allows for easy wheelbase adjustments without removing the arms from the car, making installation straightforward for your home garage or your preferred shop.
