Show original supplier description
The kit includes a robust 1.250” solid front sway bar, which is more rigid than the factory counterpart, and a 1” solid rear sway bar. The rear sway bar is heat-treated to maintain its memory longer, ensuring consistent performance, while the front sway bar is CNC bent for a precise fit and optimal geometry. Installation is straightforward as the kit is designed as a direct bolt-on and includes all necessary grade 8 mounting hardware and greaseable bushings. Available in a durable powder-coated finish in either bright red or gloss black, these sway bars not only improve performance but also add a visually appealing aesthetic to your vehicle's suspension. The kit is manufactured in the USA, reflecting a commitment to quality and domestic production. This sway bar kit is specifically designed for the 1978-1988 GM G-Body platform, including a wide range of Buick Regal, Chevrolet El Camino, Malibu, Monte Carlo, GMC Caballero, Oldsmobile Cutlass, and Pontiac Bonneville and Grand Prix models within those years.
