Elgin Industries has launched a broad new line of Elgin Pro-Stock performance valve springs engineered specifically for General Motors LS based engines. The new valve springs are optimized for use with Elgin Pro-Stock performance camshafts, including the company’s Sloppy Stage 2 hydraulic roller lift cam.
The new Pro-Stock performance valve springs include an array of advanced features designed to ensure superior durability and valvetrain performance, including:
- Micro-engineered surface finish for maximum durability
- Multilayer fatigue enhancement, eliminating potential surface defects and prolonging spring life
- Proprietary heat-treat process for added strength and optimized residual stress
- Beehive and conical spring geometries, reducing dynamic surges for exceptional valvetrain harmonics
“Elgin Pro-Stock has become performance engine builders’ go-to source for leading-edge valvetrain technologies for LS engines,” said Rick Simko, Elgin Industries National Sales and Marketing Manager. “This new line was developed in response to overwhelming demand for top-quality, street- and strip-proven performance springs manufactured by a trusted, US-based supplier.”
