Beans Diesel 210003 Billet Rocker Box — 5.9L / 6.7L Cummins
Give your 2006+ Cummins the extra room and finished look it deserves.
The Bean Machine 210003 Billet Rocker Box is a precision-machined upgrade designed for 2006 and newer 5.9L and 6.7L Cummins engines. CNC-cut from 6061-T6 billet aluminum, it delivers an extra ¼" of internal clearance—ideal when you’re running aftermarket rocker arms, high-lift valvetrain components, or larger head studs.
It bolts on with no modifications and works with both 14mm and 9/16" head studs. Installation is straightforward: it uses the factory OEM Cummins rocker box gasket for a reliable seal. Six alloy-steel socket-head screws are included.
The raw machined finish looks clean and professional under the hood, replacing the stock cast piece with a stronger, more precise component. Made in-house in Woodbury, Tennessee.
