UMI Performance 70-81 GM F-Body Upper A-arms Front Tall Ball Joints

If you're looking to seriously improve the handling and steering response of your 1970-1981 GM F-Body, like a Camaro or Firebird, these upper A-arms from UMI Performance are a critical upgrade. They're designed to give your muscle car a more connected feel to the road, reducing that vague wandering you can get from stock suspension, and they also help dial in better cornering performance. This isn't just about making the car look good; it's about making it drive better, whether you're on the street or the track.

What sets these A-arms apart is the attention to detail in their design. They incorporate a ball joint that's a half-inch taller than stock, which is a smart way to improve camber gain during cornering, giving you more grip when you need it. Plus, they add about 4 degrees of caster, which really sharpens up steering feel and helps the car track straighter. The cross shaft is made from strong 4140 CrMo steel and is offset, allowing for camber adjustments without needing a pile of shims. Inside, you'll find UMI-built Delrin bushings, known for their durability and precision, and a greasable design to keep things moving smoothly for a long time. The arms themselves are constructed from 1.250-inch DOM steel tubing, built tough right here in the USA.

These A-arms are a direct bolt-in for a wide range of GM vehicles from the era, including models like the Chevrolet Camaro, Pontiac Firebird, and even some Buick Roadmasters and Chevrolet Caprices. They come with a high-quality ball joint already installed, and you can choose between a UMI red or gloss black powder coat finish. For a complete installation, consider picking up the optional hardware kit, which includes Grade 8 bolts and nuts.
