Elgin Industries 1-piece Thickwall Pushrods

Elgin Industries new thick wall 1-piece pushrod design allows higher spring loads and RPM in performance engines according to engineers at Elgin Industries.  They have established a new standard in performance push rod technology with an exclusive line of thick-wall one-piece push rods enabling performance engine builders to achieve significantly higher dynamic loads and RPM. Elgin Pro Stock PushrodsThe 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. 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: a critical step since the pushrod to rocker arm cup interface is subjected to maximum loading
  • 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
