UMI Performance 70-81 GM F-Body Front Lower A-arms Delrin Bushings

When you're rebuilding the front end of your classic GM F-body or B-body, you're looking for parts that offer both improved handling and a solid foundation. This set of front lower A-arms from UMI Performance is designed to do just that. You get a pair of well-built A-arms, each featuring Delrin bushings and premium ball joints already installed. These A-arms are built to directly bolt onto 1970-1981 GM F-bodies like the Chevrolet Camaro and Pontiac Firebird, as well as 1978-1996 GM B-bodies such as the Chevrolet Caprice and Buick LeSabre, optimizing your vehicle's steering feel and stability.

What sets these A-arms apart is the attention to detail in their construction and design. They're made from 1.500-inch DOM steel tubing, a strong and durable material that can handle the demands of spirited driving. UMI has also incorporated caster relocation with chromoly offset cross shafts, which helps enhance straight-line stability and improves steering response. The lower spring bucket is heavy-duty, ready to accept both factory and aftermarket coil springs, and is even compatible with popular hybrid coilover setups from brands like Viking and QA1. The Delrin bushings are key here, as they significantly reduce friction compared to rubber, leading to more precise steering and a more connected feel to the road.

UMI also includes double shear swivel sway bar mounts, which work with most factory eyelet-style sway bars and UMI's own sway bar kits. They even supply mounting sleeves to accommodate both 1/2-inch standard and 14mm metric hardware, making installation more straightforward on different year models. If you're looking to dial in your classic GM's suspension for better performance on the street or track, these A-arms are a well-made option that brings a lot to the table.
