Product Details

UMI Performance is known for making well-built suspension components that improve the handling of classic muscle cars. This 1-1/4 inch solid front sway bar is a prime example, designed to give your classic GM a more modern feel on the road. It works by reducing body roll during cornering, which helps keep the front tires planted firmly on the pavement. This translates to flatter cornering and a more confident driving experience, whether you're cruising or carving through some twisty roads.

This bar is constructed from CNC bent 4140 CrMo steel, a strong material chosen for its excellent durability and strength. It comes with polyurethane bushings and endlinks to ensure a solid connection and smooth operation. The 1-1/4 inch diameter and 530 lb/in deflection rate offer a noticeable improvement in handling without making the ride too harsh. UMI offers this bar in a classic red or gloss black powder coat finish, and it's manufactured right here in the USA.

This sway bar fits a wide range of GM vehicles, including popular models like the 1970-1981 Chevrolet Camaro and Pontiac Firebird, as well as 1964-1977 A-Body cars such as the Chevrolet Chevelle and Oldsmobile Cutlass. For those looking for even more strength and a custom look, UMI also offers an optional billet aluminum bracket kit.
