Comp Cams

The OEM camshafts in your diesel truck do their jobs, but they may keep you from maximizing your truck's horsepower and torque. Comp Cams has a full lineup of camshafts and camshaft hardware that can have your diesel truck churning out more power while still getting excellent reliability. Comp's camshafts, cam retainers, and other cam hardware are perfect for Duramax builds that are going to see massive horsepower and torque and need better reliability than what the stock components provide.
