by | Mar 28, 2023 | 0 comments

Elgin Industries, a U.S.-based manufacturer of engine and chassis components for automotive, performance, commercial vehicle and other applications, 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 legendary Sloppy Stage 2 hydraulic roller lift cam.

The new Pro-Stock 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.”

The new Pro-Stock valve springs range includes:
