This camshaft is designed to fit a wide range of GM LS Gen IV vehicles, including popular models like the Chevrolet Camaro, Cadillac Escalade, and GMC Sierra. It's a direct replacement for your stock camshaft, but it's always a good idea to consult your vehicle's service manual or a trusted mechanic to ensure all supporting components are in good condition before installation. A proper engine tune is essential to get the most out of this camshaft and ensure optimal performance and reliability.
