Product Details

UMI Performance is known for building solid suspension components for muscle cars, and these upper A-arms for the 1970-1981 GM F-Body are a prime example. If you're looking to improve how your classic Camaro or Firebird handles, these A-arms are a key part of that upgrade. They're designed to add significant caster, which makes a big difference in how the car feels on the road, reducing that vague feeling and wander you can get with older steering systems. This makes driving more confident, whether you're cruising on the street or pushing it a bit harder.

What sets these apart is the strong tubular construction using 1.250-inch DOM steel, built right here in the USA. They come with UMI-built Delrin bushings, which are greasable to ensure smooth suspension movement and longevity. The offset cross shaft is made from 4140 CrMo steel and allows for camber adjustment, simplifying the process of getting your alignment dialed in just right. A high-quality ball joint is also pre-installed, making this a direct bolt-in part for your 1970-1981 F-Body, and it fits a range of other GM vehicles like the Buick Regal, Chevrolet Chevelle, and Pontiac Grand Prix from the 70s. This setup is great for both street use and more spirited driving.

When you're ready to tackle the installation, consider picking up the optional hardware kit. It includes Grade 8 bolts, washers, and lock nuts to ensure a secure mounting for both upper A-arms. These A-arms are a solid choice for anyone serious about improving their classic GM vehicle's handling and steering response.
