About this part

Product Details

COMP Cams is well-known for making a wide range of valvetrain components, and their Hustler Beehive Valve Springs are a solid option for GM 603/604 and CT525 LS crate race applications. These springs are visually similar to the popular GM LS6 "blue" valve springs, but they offer an improved design based on GM part numbers 12499224 and 12565313.

What sets these Hustler springs apart is their 4% higher seat and open loads compared to the stock LS6 springs. This increased load helps with better dynamic control of the valves, especially at higher RPMs. They also offer an extra .020 inches of lift capability, giving you a bit more headroom for performance camshafts. These are a popular choice for circle track racing where teams are looking for an edge within strict rules packages.
