COMP Cams Hustler valve springs are excellent performance upgrades in GM 603/604 and CT525 and LS based crate race applications with tight rules packages. These improved versions of the popular GM LS6 "blue" valve springs, offer a 4 percent higher seat and open loads for better dynamic control, as well as an extra .020 in. of lift capability over stock. COMP Cams Hustler valve springs are made from a high-quality wire in small batch manufacturing processes for durability, and they're even painted blue so they are visually identical to the OEM springs.
