The Melling Valve Spring Kit LS Beehive, with a seat pressure of 145 lbs at an installed height of 1.800 inches, is engineered for high-performance LS engine applications that demand enhanced valvetrain control and stability. It delivers 358 lbs of open pressure at 1.175 inches and supports a maximum valve lift of up to 0.625 inches, with a coil bind height of 1.100 inches. The beehive spring design reduces overall valvetrain mass, allowing for improved high-RPM performance and reduced risk of valve float. With a spring rate of 340 lbs per inch, an outer diameter of 1.307 inches, and an inner diameter of 0.885 inches, this kit is ideal for use with more aggressive camshaft profiles in street/strip and high-horsepower builds. Designed for durability under demanding conditions, the kit includes 16 high-quality valve springs to upgrade or replace your LS engine’s stock components.
