These rocker kits are 100% Made in the USA. All materials are from USA resources. Every machining step is performed in the USA. Every component is assembled in the USA. Quality is built into every rocker arm we make. Beginning with the selection of materials, nine different 2024-T3511 high-quality aluminum extrusions are precision machined to ensure a perfect fit for every application.

All rocker arm bodies and steel components are machined at our facility. Quality control is maintained by our expert machinists. Nothing we deliver has been made offshore. Our pins are larger, offering increased strength, and knurled to eliminate spinning, center less ground journals are counter bored and induction annealed for maximum strength. The center less ground, heat treated end is riveted to prevent them backing out of position.


Due to the reverse oiling pattern of the late model HEMI, the needs of this motor have been addressed better than any other manufacturer with years of development into a full rocker arm replacement, not just cheaper sleeves that bolt over the weaker stock rocker shafts ultimately increasing the shearing force on a rocker shaft that is already at it's limits on higher horsepower vehicles.

On your high horsepower HEMI, choosing the wrong rocker kit could be catastrophic to your engine if failure occurs under high loads or high rpm. Choosing the right roller rockers for your Hemi engine starts here.
