UMI Performance Anti-Eccentric Washers

UMI Performance anti-eccentric washers are designed to prevent unwanted alignment changes in your 5th Gen or G8 rear suspension. The 3/16 in. thick laser-cut washers fit in the exact factory location and provide a stable location for UMI (or other aftermarket) adjustable toe rods or adjustable rear lower control arms. Racing stress or hot street cornering can move the offset factory washers, causing rear alignment issues. UMI replacements are a great way to increase rear suspension reliability. Kits include four laser-cut black zinc coated washers; anti-eccentric washers should only be used on adjustable components. P/N 2518 fits rear toe rods or rear lower control arms. Four washers will work on a pair of toe rods or control arms.

Installation: Washers reuse factory GM bolts. Simply remove the factory eccentric washer and press in place the new UMI washer.
