ELGIN, Ill. — Engineers at Elgin Industries have established a new standard in performance push rod technology with an exclusive line of thick-wall one-piece rods that enable performance engine builders to achieve significantly higher dynamic loads and RPM, the company says.
The innovative new Elgin PRO-STOCK push rods are manufactured from aircraft-quality 4130 seamless steel tube with wall thicknesses of 0.137-in. (3/8-in. diameter rods) and 0.106-in. (5/16-in. diameter rods), providing the stiffest tubular-constructed push rods in the performance industry, Elgin says. By comparison, conventional one-piece performance push rods feature 0.080-in. wall thickness.
In addition to increased wall thicknesses, these new Elgin PRO-STOCK parts offer an array of advanced construction, machining and other enhancements to maximize wear resistance, strength and performance:
•Radius ends are hard-turned following heat treatment for superior surface-shape profile tolerance and finish
•220-degree radius ends for increased rocker travel
• Fully hardened within Elgin’s world-class heat-treat facilities for extreme wear resistance and strength
•Centerless ground for unsurpassed geometric precision
•Corrosion-resistant black oxide coating formulated for performance applications
