Engine builders and performance enthusiasts, these COMP Cams Magnum pushrods are serious upgrades for your build! Measuring 5/16 inch diameter with a 6.250 inch length, they're constructed from single-piece chrome moly steel with a thick 0.080 inch wall that eliminates flex under high loads. That rigid construction means more precise valve timing and better overall engine performance, especially in high-RPM applications. Whether you're building a street performance engine or something more radical, these pushrods deliver the durability and precision you need. The quality is exactly what you'd expect from COMP Cams - a brand that serious engine builders have trusted for decades. Installation requires proper measurement and setup, but once installed, these pushrods will handle whatever your camshaft profile can throw at them. Seriously, if you're doing a cam upgrade or engine rebuild, don't cheap out on pushrods - these Magnum series units provide the foundation for reliable, high-performance valve train operation.
