UMI Performance 82-92 GM F-Body 78-88 GM G-Body Bump Steer Adjuster Kit

UMI Performance is known for making well-built suspension components for classic American muscle cars. This bump steer adjuster kit is designed to tackle a common issue in performance builds: unwanted toe changes as your suspension moves up and down. By reducing this bump steer, you get more predictable handling and a more stable feel, especially when cornering or accelerating hard. It’s a direct bolt-on solution that works with your factory inner tie rods and spindles, so no drilling is required.

The kit uses a 4140 CrMo steel stud for strength, while the adjuster sleeve is made from lightweight 6061-T6 aluminum with a hard anodized finish for durability. You can fine-tune the steering geometry using the included shims, which come in three different thicknesses (0.125”, 0.1875”, and 0.250”). This kit is race-tested and built in the USA, offering a solid option for builders looking to improve their car's steering response and stability. It fits a wide range of vehicles, including many Buick Regal, Chevrolet Camaro, and Pontiac Firebird models from the late 70s through the early 90s.
