Not Yet Reviewed

COMP Cams Hustler valve springs are excellent performance upgrades in GM 603/604 and CT525 LS 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 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.
