UMI Performance 70-81 GM F-Body Upper A-arms Front Adjustable

UMI Performance is known for making well-built suspension components for classic American muscle cars. For your 1970-1981 GM F-Body or 1978-1996 GM B-Body, these adjustable upper A-arms are designed to significantly improve your car's handling and steering feel. They offer a great balance between performance for spirited driving or track days and the versatility needed for street use.

These A-arms are constructed from strong 1.250-inch DOM steel tubing, built right here in Philipsburg, PA. They feature a 4140 CrMo cross shaft for added strength and are designed to be shorter than stock. This shorter design helps reduce the need for shims when setting up aggressive racing alignment specs, and they provide an adjustable camber range from -0.5 to -2.5 degrees. The inclusion of rod ends minimizes stiction, allowing for more responsive steering inputs and consistent performance, especially beneficial for drag racing. You'll notice an improvement in steering feel, with an added 5 to 6 degrees of caster that helps reduce wandering on the highway. For even more dramatic results, combining these with UMI's lower A-arms can achieve 8 to 10 degrees of positive caster.

These A-arms come with a thick, laser-cut ball joint plate and a premium ball joint already installed, making them a direct bolt-in replacement. They are available in a UMI red or gloss black powder coat finish. This is a direct bolt-in upgrade for a wide range of vehicles, including the Chevrolet Camaro, Pontiac Firebird, Buick LeSabre, and Chevrolet Caprice. They are 100% manufactured in the USA, ensuring a high level of quality assurance.
