GM Technician Installing A Replacement Sheet Metal Part

Sheet Metal

Beauty beneath the surface.

A high-quality finish for Chevrolet, Buick, GMC, and Cadillac vehicles starts with GM Original Equipment sheet metal from GM Genuine Parts. Only GM Genuine Parts offers replacement sheet metal designed and constructed with GM-specific properties, thickness, and stamping features for consistent, predictable performance in a collision, and seamless performance with GM vehicle safety systems. Using GM OE sheet metal parts can help you to restore a damaged vehicle to its pre-collision condition.

Sheet Metal Replacement Part in a GM Factory

Sheet metal from GM Genuine Parts is also the only replacement sheet metal to benefit from the GM OE ELPO (electrocoat primer) process. After an eight-step pre-treatment, organic paint solids are electroplated onto bare metal surfaces to create a barrier that resists water, salt, or other corrosive threats.

Whether ELPO primed in original black or new green, sheet metal from GM Genuine Parts delivers GM-factory form and fit.

Not all parts are created equal. While GM Genuine Parts and ACDelco offer GM OE parts designed, engineered, tested, and backed by General Motors, alternatives from other sources may fit poorly, exhibit durability or corrosion problems prematurely, and perform below OE standards. Exercise your right to discuss using GM OE parts with your insurer and keep your GM a GM.

The extensive GM Genuine Parts distribution network helps ensure local availability of replacement sheet metal and other GM Original Equipment parts. GM OE sheet metal replacement parts are also carefully packaged and shipped in part-specific boxes, designed to protect and preserve primed surfaces, to help ensure they arrive damage-free and ready for prep.


When you choose GM OE sheet metal you not only get exceptional quality, fit and finish, you get the peace of mind that comes with a Limited Lifetime Warranty.
