Chevrolet Performance Parts is a brand that offers street and racing performance parts for your Chevrolet. Though Chevrolet Performance Parts has a long and successful past, it has seen many changes over time (including a 2012 rebrand, formerly called GM Performance Parts). From a small system of parts suppliers, it expanded into an entire brand supported by numerous dealers all over the country. From the early days of producing parts for experimental vehicles to today’s line of aftermarket accessories, GM Performance Parts have expanded into new categories and markets while continuing to produce high-quality parts. From basic crate motors and engine blocks to high-end, fully-assembled motors, Chevy Performance has everything you need to get your performance project started.
