2001-2016 Duramax 6.6L Manton Series 3 Pushrods Set of 16

Upgrade your 6.6L Duramax Diesel Pushrods for enhanced strength and valve train stability. OEM pushrods are insufficient beyond stock use, risking reduced power and engine damage under stress. Choose from 3/8 or 7/16 diameter pushrods made of 4130/4135 seamless Chromoly tubing with various heat treatments and billet steel tips. CNC-machined 86L20 bar stock tips offer superior impact and wear resistance, prolonging pushrod life and boosting valve train performance. Opt for larger diameter tubing to double loading capacity without cylinder head binding, ideal for Duramax engines.

Upgrade to our Series 5 pushrods for competition engines, offering 105,000 p.s.i. tensile strength over Series 3, improving valve timing accuracy and surge threshold. Trusted in top-tier motorsports, our Series 5 pushrods ensure durability and performance longevity.

For engines needing custom pushrod lengths, use our tools to replicate OEM specs, maintaining rocker arm geometry and valve bridge contact. Incorrect lengths can disrupt oil flow, leading to lifter damage and camshaft wear. Pushrods are crucial for optimal valve train function and durability.
