Overview

The XDP 3/8" Street Performance Pushrods are a valvetrain upgrade for your 2019-2022 Ram 6.7L Cummins. Factory pushrods may not withstand increased valve spring pressures, cylinder pressures, or higher RPMs found in modified engines. These XDP pushrods are constructed from 4130/4135 chromoly tubing for enhanced rigidity and reduced flex.

Show original supplier description

In modified Cummins applications, the factory pushrods are not always adequate to handle the increased stress from higher cylinder pressures, valve spring pressures, and elevated engine RPMs. Even if your original pushrods do not show visible damage, they may still be too flexible for modified engines, potentially leading to power loss and premature valvetrain component failure. This material is cold-drawn over a mandrel to improve rigidity and minimize flex. The pushrod tips are CNC machined from 86L20 bar stock, which is then core hardened and triple-tempered to enhance impact and wear resistance. These design and material choices aim to extend the life of the pushrods and improve overall valvetrain performance. These pushrods are designed for stock to moderate builds and are capable of supporting over 500 horsepower. They feature a 3/8" diameter and a tensile strength of 170,000 PSI. The overall length is 10.150".

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
