UMI Performance 93-02 F-Body Front Upper A-Arm Mounts Adjustable Factory

The UMI Performance adjustable upper A-arm mounts are built from robust 3/16” laser-cut USA steel, offering a strong replacement for your factory GM mounts. Unlike the original design that could trap water and lead to rust, UMI’s fabricated mounts feature a design that allows water to drain freely. This can help extend the life of your front shocks and keep the mount itself in better condition over time.

These mounts also give you the ability to fine-tune your front suspension geometry. They include the factory A-arm mounting holes, plus additional holes that allow you to raise or lower the A-arm mounting point by 3/8 of an inch. Adjusting the roll center height can increase steering responsiveness and improve camber gain, making your alignment perform better during cornering. For street and drag applications, using the center hole keeps the A-arm in its factory position. These are a direct bolt-on part, meaning no drilling or welding is required for installation, and they work with both factory and aftermarket A-arms.
