COMP Cams Stage 1 LST 186/200 Solid Roller Camshaft 2000+ GM 6600/6.6L Duramax Diesel

COMP Cams is well-known for making performance valvetrain components, and their LST Camshaft Series takes that reputation a step further with advanced lobe designs. This Stage 1 LST camshaft is specifically designed for GM 6.6L Duramax Diesel engines from 2001 through 2016, including popular models like the Chevrolet Silverado 2500 HD and GMC Sierra 3500 HD. It's built to give you a noticeable boost in power and torque across the entire RPM range, offering instant response that feels much better than stock.

What makes this camshaft stand out is its "Low Shock Technology." This means the lobe profiles are engineered to maximize airflow into the engine, which helps reduce exhaust gas temperatures (EGTs) and keeps the engine stable even at higher RPMs. Plus, these updated profiles are gentler on your valve springs, meaning they'll last longer and maintain their load better, so you won't need to upgrade them. This Stage 1 camshaft is a "No Springs Required" (NSR) grind, meaning it works well with your factory valve springs and can even be used with a stock tune, making installation more straightforward.

If you're looking to get more out of your Duramax diesel without the complexity of a full valvetrain overhaul, this camshaft is a solid option. It's designed to be a direct replacement for your factory camshaft, and when paired with appropriate tuning, it can significantly change how your truck performs. Remember, this camshaft is not CARB approved and cannot be shipped to California.
