UMI Performance 71-72 GM A-Body Bump Steer Adjuster Kit

If you're looking to get the most out of your 1971 or 1972 GM A-body's suspension, especially for performance driving like road racing or autocross, addressing bump steer is key. Bump steer is when your wheels change direction (toe angle) as the suspension moves up and down. This kit from UMI Performance is designed to help you dial that out, making your car track straighter and feel more precise.

This kit replaces the factory outer tie rod connection with a stronger, adjustable setup. It uses a beefy 5/8-inch bolt for increased strength over the stock tapered stud, which is crucial when you're pushing the car hard. The adjuster itself is made from lightweight 6061-T6 aluminum with a durable black anodized finish, and it comes with a variety of shims so you can fine-tune the tie rod height to minimize toe change during suspension travel. It's designed to work with your factory inner tie rods and spindles, though it does require drilling the spindle to accept the larger bolt. This is a race-proven design, manufactured and tested in Philipsburg, PA, USA.

This kit fits a range of popular GM A-body models from 1971 and 1972, including the Chevrolet Chevelle, Pontiac GTO, and Buick Skylark. While it's a bolt-on installation for the most part, remember that drilling the spindle is a necessary step to install the larger 5/8-inch bolt. Once you've got it set up, you'll notice a more connected feel from your steering system.
