Shop New OEM camshaft components and related engine hardware for GM vehicles. Our factory-original engine parts are sourced from GM surplus — covering Gen V LT engines (L83, L86, LT1, L8B) and other GM platforms.

Camshaft specifications — lobe lift, duration, and phaser travel — are precisely matched to the engine's compression ratio, combustion chamber design, and ECM calibration. OEM camshafts maintain these specifications to ensure proper valve timing, fuel economy, and emissions compliance throughout the engine's service life.

Always inspect lifters, pushrods, and timing components when replacing camshaft components. Verify part numbers against your specific engine RPO code before ordering.
