Hemi and LS Engine Conical Valve Springs

Elgin Industries Introduces Elgin PRO-STOCK® Conical Valve Springs for GM LS and Chrysler Hemi Performance Engines

Elgin, IL…Elgin Industries, one of the world’s leading manufacturers of engine and chassis components for the automotive, performance, heavy duty and industrial markets, 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 superior performance and durability while accommodating the peak valvetrain RPMs associated with high-performance camshafts.

Hemi Engine and LS Engine Performance Conical Valve Springs

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 super-finished surface optimizes the springs’ max lift capability and durability.
