Summit Racing™ HDR premium thick-wall pushrods are a great upgrade for your engine. Factory pushrods (and even .080 wall aftermarket versions) act like a pogo stick in a running engine. Not only is static spring pressure working against them, it's also the valvetrain inertial mass increasing with RPM. This reduces power and valvetrain life. While a .080 thin-wall pushrod may not break, it doesn't mean it's the best option. Enter the HDR's. Summit™ used FEA (Finite Element Analysis) in the initial testing. We didn't just compare them to thin-wall welded-ball factory pushrods, but with aftermarket models, as well. The results speak for themselves! * The Summit™ HDR 5/16 x .105 wall pushrods have 20 percent less stress and 25 percent less deflection than a typical 5/16 x .080 chromoly pushrod * The Summit™ HDR Pro LS 11/32 x .120 wall have 25 percent less stress and 28 percent less deflection than a typical 5/16 x .080 wall chromoly pushrod * The Summit™ HDR 3/8 x .135 pushrods commonly used in big blocks has 15 percent less stress and 20 percent less deflection than a typical 3/8 x .080 wall chromoly pushrod Summit Racing™ added other high-end features like 210 degree ball ends to cope with extreme lobe lift and clear the rocker and are available in multiple lengths. * HDR 5/16 pushrods are offered in common LS, SBC, and SBF lengths * HDR Pro LS 11/32 pushrods add .030 diameter AND .120 wall thickness over a 5/16. Although most LS engines came with 5/16 pushrods, 11/32 pushrods fit any stock or aftermarket cylinder head. The added thickness adds much needed strength to any LS cam swap or engine build. Being available in .025 in. increments allows for fine tuning of hydraulic lifter preload with the LS's non-adjustable rockers. * HDR 3/8 pushrods fit the LS7 and common BB Chevy combinations. They have .135 wall thickness for maximum strength. Pushrods are some of the best horsepower-per-dollar components in your engine, so step up to the HDR's for your build!
