1.077/1.282 OD Beehive Hustler Valve Spring; 1.800" Installed Height - Single

The COMP Cams® Hustler™ Valve Spring is an improved version of the popular GM LS6 “blue” valve spring. It's based on the popular GM part #12499224 and #12565313 LS6 springs but with 4% higher seat and open loads for better dynamic control, as well as an extra .020” of lift capability. It's even painted blue so it is visually identical to the OEM springs – an excellent performance upgrade in GM 603/604 and CT525 LS crate race applications with tight rules packages.
