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

UMI Performance is known for making well-built suspension components that improve the handling and performance of classic American cars. If you're looking to give your 1970-1981 GM F-body or 1978-1996 GM B-body a serious upgrade in steering feel and stability, these front lower A-arms are a solid choice. They're designed to optimize your vehicle's handling, especially at higher speeds, making a noticeable difference whether you're cruising or hitting the track.

These A-arms are constructed from tough, 1.500-inch USA-made DOM steel tubing, which means they're built to last. They feature a relocated lower ball joint that adds 2 degrees of caster, helping to improve straight-line stability and give you a more connected feel to the road. Inside, you'll find Delrin bushings, which significantly reduce friction compared to rubber, leading to more precise steering response. They also come with a heavy-duty spring bucket that works with both factory and aftermarket coil springs, including popular hybrid options like Viking and QA1, giving you flexibility for your build. The double shear sway bar mounts are also a nice touch for added strength.

When you're ready to install these, UMI includes mounting sleeves to accommodate either the 1/2-inch hardware found on 1970-1974 F-bodies or the 14mm metric hardware used on 1975-1981 models. You can also opt for a new hardware kit if you prefer. These A-arms are a direct bolt-in replacement, simplifying the installation process.
