Comp Cams 42030506901 Features:

• Comp Cams Xtreme Race G2 Pushrod (PN 42030506901) delivers race-proven valvetrain stability with a 7.500 in. length, 5/16 in. diameter, and a stout .106 in. wall for high-lift, high-spring-pressure builds.
• Built from 4130 aircraft-quality seamless Chromoly tubing and finished in black oxide, it’s engineered for maximum stiffness and durability—up to 40% more column strength than typical .080 in. wall pushrods.
• The 210-deg radius single-end tip improves rocker arm adjuster clearance in tight or compromised-geometry setups, helping you maintain proper motion and reduce interference when things get aggressive.
• Heat-treated and carburized to 58 RC hardness, plus centerless-ground for tight runout, it’s designed to stay straight, consistent, and guide-plate friendly through sustained RPM and abuse.
• Choose the Xtreme Race G2 upgrade when standard pushrods deflect: premium materials, precision manufacturing, and serious strength in a 5/16 in. package—built to keep your valve train under control.
