DSE Front Sway Bar Kit / Chassis Brace Kit - 1-3/8in Diameter (031408DS) - 1978-1988 GM G-Body
Take the flex and body roll out of your classic G-Body with the Detroit Speed Front Sway Bar / Chassis Brace Kit, part number 031408DS. Designed for 1978-1988 GM G-Body applications, this integrated handling package combines a 1-3/8-inch tubular front sway bar with a chassis brace system to attack two major weaknesses of the factory chassis. The larger sway bar increases roll resistance for flatter, more controlled cornering, while the included brace triangulates the front crossmember to reduce chassis deflection and create a more solid foundation for the front suspension.
Detroit Speed developed the 031408DS through extensive testing, finding improved performance on cars with stock suspension and optimal results when combined with other Detroit Speed components. The tubular sway bar has a 790 pounds per inch anti-roll bar rate and is supplied with greaseable polyurethane bushings, mounts, and end links. Detroit Speed bends its sway bars in-house for greater control over manufacturing quality, while the included chassis brace adds another level of front-end rigidity. For G-Body owners who want more than a simple sway bar swap, 031408DS provides roll control and chassis reinforcement in one coordinated package.
