2017-26 6.6L Duramax L5P Pushrods Series 3
Introducing 6.6L Duramax Diesel Pushrods: OEM pushrods lack strength beyond stock vehicle use. Exceeding operational limits can lead to power loss, fuel inefficiency, or engine damage.
We offer 3/8 and 7/16 diameter pushrods for enhanced strength and valve train stability. Crafted from 4130/4135 seamless Chromoly tubing with billet steel tip ends. CNC machined 86L20 bar stock tips are core hardened and triple tempered for durability. Larger diameter pushrods spread load, preventing binding in cylinder head ports. 7/16 diameter provides nearly twice the loading capacity before deflection. Opt for larger diameters like 7/16 for superior performance in Duramax engines.
Upgrade to Series 5 for competition engines, boosting tensile strength by 105,000 p.s.i. Enhanced rigidity ensures precise valve timing and prevents surging. Series 5 pushrods are unmatched in strength, ideal for various high-performance applications.
For custom length needs, our pushrod tools ensure accurate replication of OEM specifications. Proper length maintains stock rocker geometry, optimizing valve train operation. Incorrect lengths can disrupt oil flow to lifters, risking damage to components. Pushrods are critical for valve train performance and longevity.
