COMP Cams Camshaft 99-08 Chevrolet V8 Small Block Gen III/IV 6.0L/364

COMP Cams is well-known for making performance valvetrain components that help you get the most out of your engine. This Stage 2 Thumpr camshaft is designed for GM's Gen III and Gen IV LS engines, specifically the 4.8L, 5.3L, 6.0L, 6.2L, and even the 7.0L variants found in a wide range of trucks and cars from 1999 through 2008, and even later in some models. It's a larger version of their popular No Springs Required (NSR) Thumpr design, making it a solid choice for more heavily modified truck applications.

This camshaft is intended for trucks that have already seen some upgrades, like headers, a torque converter, and gear changes. The 226/237 duration specs mean it's built for improved airflow and power, especially at higher RPMs, while still maintaining reasonable drivability for a performance camshaft. It's a hydraulic roller design, which is standard for these LS engines and helps reduce friction compared to older flat-tappet cams. While it's a larger profile, it's designed to work with the factory spring setup in many cases, simplifying installation.

This camshaft fits a broad spectrum of GM vehicles, including popular models like the Chevrolet Silverado, GMC Sierra, Cadillac Escalade, and Chevrolet Corvette. If you're looking to wake up a modified LS truck engine and want a noticeable bump in performance, this Stage 2 Thumpr cam from COMP Cams is a well-built option to consider. Keep in mind that this camshaft is not CARB approved and cannot be shipped to California.
