Description

The Rustbuster Frameworks RB7403L is an over-axle frame repair kit designed for the driver's side of various GM SUVs from 2000-2020. Made from heavy-duty 11 gauge steel, it is laser-cut and CNC bent for a precise fit. This kit helps address common rust issues by capping the frame where it curves over the rear axle, retaining the factory bump stop, and including an additional sway bar end link bracket.
