JNK Pushrods for the 6.0L and 6.4L Powerstroke

Upgrade the valvetrain in your 6.0L or 6.4L Powerstroke with JNK Chromoly Pushrods. Factory pushrods were designed around stock power and boost levels, making them more susceptible to flexing as cylinder pressure, RPM, and valve-spring pressure increase.

JNK pushrods feature a revised-length, 3/8-inch design manufactured from hard-drawn 4130/4135 seamless chromoly tubing. Their increased diameter and thicker construction provide greater rigidity and nearly 50% more load capacity than the factory 11/32-inch pushrods—all while maintaining proper cylinder-head clearance.

Whether you’re rebuilding a dependable work truck or strengthening a high-performance Powerstroke, these pushrods help deliver the valvetrain stability needed for demanding applications.
