Upgrade your 12 Valve Cummins pushrods for improved valve train stability and performance. Stock 3\/8 diameter pushrods, nearly 11 inches long, aren’t adequate beyond stock applications. When pushrod stress exceeds reasonable limits, OEM pushrods can’t support additional valve train loads.\u003c\/p\u003e\u003cp\u003eWe offer 3\/8 and 7\/16 diameter 3-piece pushrods made from 4130\/4135 seamless Chromoly tubing Heat treated. Standard billet steel tip ends are CNC machined from 86L20 bar stock, then core hardened and triple tempered for durability. These materials and treatments extend pushrod service life and enhance valve train performance. Our engineering adapts to your engine’s needs, ensuring optimal fit and function.\u003c\/p\u003e\u003cp\u003eWe prioritize larger diameter pushrods to distribute loads without cylinder head port binding. The 7\/16 diameter nearly doubles loading capacity before pushrod deflection, making it ideal for Cummins engines.
