Elgin Industries has introduced premium Elgin PRO-STOCK conical valve springs engineered for General Motors LS Series and Chrysler Hemi performance engines. The new PRO-STOCK springs (#RV-107228Q16) feature a next-generation conical design that ensures performance and durability while accommodating the peak valvetrain RPMs associated with high-performance camshafts.
Unlike cylindrical and beehive springs, Elgin PRO-STOCK conical valve springs help stabilize valvetrain dynamics and provide superior damping without wear, interference contact and other concerns. With a progressively narrower diameter from bottom to top, each coil of a conical spring has its own frequency, dramatically reducing load, increasing the spring’s peak RPM capabilities and enabling customers to use a more aggressive camshaft. A superfinished surface optimizes the springs’ max lift capability and durability.
Specifications of these new springs, sold in sets of 16, are below:
