Show original supplier description
The PSI Performance Springs PSI-1515ML is a set of beehive valve springs engineered for high-performance LS engines, supporting up to .650" lift. These springs undergo an enhanced nitriding process, boosting surface strength and providing improved resistance to fatigue and wear, which extends their lifespan. These springs are specifically recommended for Circle Track and Road Circuit racing due to their enhanced durability. However, they are not recommended for drag racing applications where maximum core hardness is preferred over endurance. Key specifications include 140 lbs at 1.950" installed height, 405 lbs at 1.300" installed height, and a coil bind height of 1.225". The springs have an outer diameter of 1.290" and an inner diameter of .630". The set includes 16 springs. For Hemi applications (2012+ 5.7L, 6.4L, and 6.2L), these springs are designed for use with stock valve locks and retainers. It is important to note that these are not compatible with Redeye/Demon valves.
