Building a performance engine? These Manley chrome moly pushrods are exactly what you need for reliable, high-RPM operation. Made from 4130 chrome moly steel, these aren't your average pushrods - they're built to handle the demands of racing, high-performance street engines, or off-road use. The 5/16 inch diameter provides excellent strength without adding unnecessary weight, and the 6.600 inch length is specifically designed for small block Chevy applications. What sets these apart is the careful manufacturing process - the ends have exact radii and consistent wall thickness throughout, which means better oil flow and reduced stress points. This set includes 16 pushrods, so you've got everything needed for your V8 build. Made right here in the United States by Motor State Distributing, a company with decades of experience in high-performance components. The package weighs about 1.91 pounds and comes in a 13x4x2 inch box that's easy to store until you're ready for your build. Whether you're upgrading your existing engine or building something new from the ground up, these pushrods deliver the quality and reliability that serious engine builders trust. Don't compromise on valvetrain components - your engine's performance depends on it!
