UMI Performance 70-81 GM F-Body Front A-arm Kit Delrin Bushings Adj Tall Ball Joints

If you're looking to seriously upgrade the front suspension on your 1970-1981 GM F-Body, this performance A-arm kit from UMI Performance is a solid choice. It's designed to give you a noticeable improvement in steering feel and high-speed stability by relocating the upper and lower ball joints to add caster. This kit is built for a direct bolt-in installation on models like the Chevrolet Camaro and Pontiac Firebird, and also fits a range of other GM vehicles from the late 70s through the mid-90s, including Buick LeSabre and Chevrolet Caprice.

What sets this kit apart is the attention to detail in its design. The upper ball joint is moved rearward to add up to 6 degrees of caster potential, while the lower ball joint is moved forward by 2 degrees. This combination significantly enhances steering feel and straight-line stability. You also get a taller upper ball joint, which helps improve camber gain during hard cornering, giving you better traction. The adjustable upper A-arms use rod ends, making alignment adjustments much easier than dealing with shims. UMI uses their own Delrin bushings for improved steering response and reduced deflection, paired with Teflon-lined rod ends for smooth operation. The heavy-duty spring bucket is built to accept factory and aftermarket coil springs, as well as popular hybrid coilover units from brands like Viking and QA1.

This kit also includes UMI's double shear swivel sway bar end links, which work well with UMI's own sway bars or most other aftermarket sway bars that use a factory eyelet style mount. The DOM steel tubing construction, laser-cut reinforcement plates, and USA-made quality mean this kit is built to last. It's a comprehensive package designed to blur the lines between race car handling and street car comfort.
