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

If you're looking to significantly 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 solid choice. They're designed to address common handling issues by adding positive caster, which helps your car track straighter and reduces that vague feeling in the steering wheel, especially at higher speeds. Plus, they come with a ball joint that's a half-inch taller than stock, a smart move that helps achieve better camber gain when cornering, giving you more grip when you need it most.

These aren't just simple replacements; they're a well-built upgrade. Constructed from strong 1.250-inch DOM steel tubing right here in the USA, they're built to last and handle the demands of spirited driving or track use. UMI includes their own greaseable Delrin bushings, which offer smooth suspension movement and are known for their durability. The offset cross shaft, made from 4140 CrMo steel, is a key feature that allows for camber adjustments without needing a stack of shims, making alignment easier. They also incorporate a polyurethane bump stop for controlled rebound.

This kit is a direct bolt-in for a wide range of GM vehicles from 1970 to 1981, including popular models like the Chevrolet Camaro, Pontiac Firebird, and even some Buick LeSabre and Chevrolet Caprice models from specific years. While they fit many vehicles, they are specifically engineered for the GM F-Body platform to maximize their benefits. An optional hardware kit is available if you need new Grade 8 mounting bolts and nuts.
