Door Handle

Browse New OEM exterior and interior door handles for GM vehicles. Our factory-original handles are sourced from GM surplus — the correct color, finish, and grip configuration for your specific model and trim level, in new and uninstalled condition.

OEM door handles are molded and finished to the exact color and texture of your vehicle's interior and exterior. Aftermarket handles often exhibit color mismatch, fitment gaps, and inferior latch mechanism integration. Our OEM handles install directly with no modification and operate identically to the original.

Exterior door handles are available in body-color painted and chrome finishes. Verify your vehicle's door handle style and color code before ordering.
