Overview 

The Melling 500704 pushrod is engineered for precision and durability in GM Gen III/IV LS engines, including 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L applications. Measuring 7.400 inches in length with a 5/16-inch diameter and a .080-inch wall thickness, it provides excellent strength and resistance to flex, making it ideal for use with high-lift camshafts and moderate valve spring pressures. Constructed from high-quality chromoly steel, the pushrod delivers long-lasting performance and consistent valvetrain geometry. Its ball-end design on both ends ensures compatibility with factory or aftermarket rocker arms, and precision machining guarantees tight tolerances for reliable operation across various engine builds.
