Product Description

The QA1 52877 is a performance front sway bar engineered specifically for 1978-1988 GM A-Body and G-Body vehicles, including the Monte Carlo, Malibu, El Camino, Caballero, Buick Regal, Oldsmobile Cutlass, Pontiac Grand Prix, and Bonneville. Manufactured from lightweight hollow-core 4130 chromoly steel with 3/16 in. wall tubing, it delivers significantly more torsional stiffness than the factory bar without adding unnecessary weight. The 1-3/8 in. diameter is precision-tuned for the torsional demands of this platform, reducing body roll during cornering and braking for a flatter, more controlled driving experience.

Installation uses the factory sway bar mounting locations for a true bolt-on fit, and the kit includes greaseable graphite polyurethane bushings and high-quality zinc-plated hardware for a complete, ready-to-install upgrade. The gloss black powder-coat finish adds durability and a clean appearance under the car. Whether you're building a street performance machine, a pro-touring restomod, or just refreshing a worn-out factory bar, the QA1 52877 is a direct-fit solution for the entire 1978-1988 GM A/G-Body family and is an ideal complement to the QA1 52878 rear sway bar.
