Improve the performance and reliability of the valvetrain in your truck when you install the XDP Street Performance Pushrods (3/8") XD399. The factory pushrods are unable to support the increased valve spring pressures, cylinder pressures, and higher RPMs of a modified diesel engine. Even if your pushrods don’t show any outward signs of failure, that does not mean they are able to handle the additional stress. The stock pushrods can flex excessively even in mildly built applications, leading to power loss and premature valvetrain wear or failure.
The XDP Street Performance Pushrods are manufactured to XDP's exacting specifications. These 3/8” diameter pushrods feature seamless 4130/4135 chromoly tubing that is cold drawn over a mandrel for greater rigidity and to minimize flex. The CNC machined tips are built from 86L20 bar stock that is triple tempered and core hardened to provide greater wear and impact resistance. These manufacturing processes and high-quality materials means these pushrods deliver improved valvetrain performance and longer service life. Sold as a set of 12.
