PUSHROD, XTREME RACE G2 8.700" LENGTH 5/16" DIA .106" WALL 210 RADIUS SET 12 The COMP Cams Xtreme Race G2 pushrod set provides a high-stiffness valvetrain solution. This set of sixteen precision-formed, high-strength pushrods is designed to minimize deflection under elevated valve-spring loads and high-RPM operation, ensuring stable lifter-to-valve motion and maintaining accurate valve timing across the operating range. Engineered from premium 4130 aircraft-grade seamless chromoly steel and built around a stout 5/16-inch diameter, these one-piece, centerless-ground pushrods deliver uncompromising stiffness—dramatically cutting deflection and outperforming stock components when the power comes on. Precision-machined 210-degree radius tips ensure the rocker arms clear even the most aggressive high-lift camshafts, preserving razor-sharp valve timing and consistent lifter preload when your cam profile demands more. A durable black-oxide finish fights corrosion and helps retain vital oil at contact points, making this pushrod set a true race-ready upgrade built to thrive in hard-driven street builds and demanding track environments.
