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

If you're working on a 1970-1981 GM F-body or a 1978-1996 GM B-body, UMI Performance offers these adjustable upper A-arms to really dial in your front suspension. These aren't just replacements; they're an upgrade designed to give you more control and a better feel for the road, whether you're hitting the drag strip or just enjoying a spirited drive on winding roads. They help improve steering precision by adding significant caster, which makes your car feel more stable at speed and return to center more readily after a turn. Plus, the adjustability means you can fine-tune your camber and caster settings to get the alignment exactly how you want it.

These A-arms are built tough. They use strong, tubular DOM steel construction, measuring 1.250 inches in diameter, and feature a 4140 CrMo cross shaft for added strength. This robust build is designed to handle the demands of performance driving. The shorter design can also reduce the need for shims when setting up aggressive racing alignments, offering a camber range from -0.5 to -2.5 degrees. The rod ends used in their construction minimize stiction, which translates to more responsive steering inputs and consistent performance, especially important for drag racing. They're designed as a direct bolt-in, making installation more straightforward. For the best results, UMI recommends pairing them with their lower A-arms to achieve up to 8 to 10 degrees of positive caster.

These adjustable upper A-arms are proudly manufactured in Philipsburg, PA, USA, ensuring solid build quality. They come with a thick, laser-cut ball joint plate and a premium ball joint already installed, simplifying the installation process. You can choose between a classic UMI red or a gloss black powder coat finish to match your build. While these are great for race use, they're also street-worthy, offering a noticeable improvement in steering feel and stability without sacrificing too much comfort.
