JESEL 6.4L POWERSTROKE FORGED STEEL ADJUSTABLE ROCKER ARM SYSTEM

JESEL 6.4L Powerstroke Forged Steel Adjustable Rocker Arm System

We proudly offer the strongest and highest quality rocker arm system for the Powerstroke platform. Developed with Jesel, this kit includes shaft-mounted, forged steel adjustable rocker arms, sturdy rocker stands, and billet tool steel valve bridges.

This system bolts on with zero clearance or modifications needed. Uniquely, you can bolt the rocker stand to the heads and add or remove rocker arms without taking off the head studs or bolts. This feature simplifies installation and maintenance significantly.

Jesel rockers come with our custom KDD chromoly pushrods. They also work with Jesel Solid Roller Link Bar Lifters and custom ground solid roller cams. These parts are co-designed with top valvetrain experts from racing, ensuring race-winning performance.

Note that the Jesel rocker system’s modified geometry requires different length pushrods. You can purchase these pushrods for $299 when you buy the Jesel Rocker System.

For complete performance, we recommend the full solid roller package. It includes the Jesel adjustable rocker arm system, solid roller cam, solid roller lifters, and pushrods—all matched for easy bolt-on installation.
