Product Details

COMP Cams has a long history of making serious performance valvetrain parts, and this camshaft is built on that reputation. This is a solid roller camshaft specifically for the GM 6.6L Duramax diesel engine. It’s designed to give you improved torque and horsepower, while also optimizing fuel mileage, making it a great choice for trucks that do a lot of heavy towing or for mild modifications.

The 185/188 duration on the intake and exhaust sides, along with the solid roller design, helps the engine breathe better. This updated profile is intended to work well with common modifications and is a popular choice for owners looking to get more out of their Duramax. COMP Cams always recommends checking piston-to-valve clearance when installing any camshaft. Modern engine designs can have tight clearances, so ensuring at least .080 inches on the intake and .120 inches on the exhaust side is crucial to prevent interference and potential engine damage.

This camshaft fits a wide range of GM trucks and SUVs, including models like the Chevrolet Silverado 2500 HD, GMC Sierra 3500 HD, and Chevrolet Express vans from 2001 through 2016. It’s a solid option for Duramax owners looking for a noticeable improvement in performance and efficiency, especially for towing applications.
