Fits: 2001 thru 2016 Chevy Silverado/GMC Sierra 2500HD/3500HD LB7/LLY/LBZ/LMM/LML Duramax Diesel

Due to the marginal column strength, Manton feels OEM pushrods are not adequate for anything other than a Stock vehicle. When the stress on the pushrod surpasses what is considered a reasonable window of operation, the OEM pushrod is not designed to support the additional load that the valve train system is experiencing .
If your engine is seeing a high amount of RPM, boost, nitrous, these Series 5 pushrods will provide an additional 105,000 p.s.i. tensile strength over our Series 3. The increase in rigidity will provide further accuracy of the valve timing and raise the point at which the valve train begins to surge. Manton Series 5 pushrods are the strongest most durable chromoly pushrods ever produced .This has been proven in their top fuel, blown alcohol, sprint car, cup , dirt short course, Baja, tractor pulling and offshore marine champions, year after year. Now they are available for your Duramax engine.

To provide increased pushrod column strength and valvetrain stability, Manton offers both 3/8 and 7/16 diameter “3 Piece” pushrods. Manton pushrods are manufactured with 4130/4135 seamless Chromoly tubing with a variety of heat treating conditions and wall thickness’ available, all coming standard with their billet steel tip ends. These tips have been CNC machined from 86L20 bar stock that are then core hardened and triple tempered, providing increased impact and wear resistance. This combination of materials and heat treatment procedures will extend the service life of the pushrod, while improving overall performance of your valve train. Manton's versatility in engineering and design allows them to manufacture a product that will enhance the specific combination of your engine.
