UMI Performance 1978-1988 GM G-Body Rear Frame Notching Kit (Weld-In) - 3061

Fits select 1978-1988 GM G-Body vehicles including Buick Regal, Chevrolet Monte Carlo, El Camino, Malibu, Oldsmobile Cutlass, and Pontiac Grand Prix.

The UMI Performance P/N 3061 frame notch kit provides a professional solution for narrowing the rear upper frame rails on the GM G-Body platform. This modification is essential for enthusiasts looking to install wider rear tires that would otherwise interfere with the factory frame rails. The kit is engineered to maintain structural strength while creating the necessary clearance for aggressive wheel and tire fitments.

Each component is laser-cut from 1/8-inch premium steel to match the frame contour, featuring a slight intentional overhang to facilitate easier welding with a standard MIG welder. The kit also includes end enclosures to bridge the gap between the modified section and the original frame rails for a clean, secure finish.
