Tameless Performance Billet Rocker Box 06-24 Dodge Ram 5.9L/6.7L Cummins

Upgrade the valvetrain sealing, rigidity, and appearance of your 5.9L or 6.7L Cummins with the Tameless Performance Billet Rocker Box. CNC-machined from solid 6061-T6 billet aluminum, this one-piece rocker box is designed as a direct replacement for the factory cast-aluminum unit while providing improved clamping force, enhanced sealing, and a substantial weight savings. The factory rocker box weighs approximately 5.95 lbs, while the complete Tameless Performance billet rocker box weighs approximately 4.8 lbs. The lighter design is particularly beneficial for performance and competition-oriented diesel builds while maintaining the strength and rigidity needed for demanding Cummins applications. 6061-T6 Billet Aluminum Construction The Tameless Performance rocker box is CNC-machined from solid 6061-T6 billet aluminum for precise fitment and increased rigidity. Unlike the factory cast design, the billet construction is engineered to resist warping and provide a consistent sealing surface between the rocker box and cylinder head. Improved Sealing and Clamping The billet design provides improved clamping for the rocker box gasket, helping reduce the potential for oil leaks associated with warped or damaged factory cast components. The one-piece construction provides a rigid mounting platform and is compatible with both OEM and aftermarket valve covers. Head Stud Clearance The Tameless Performance billet rocker box is designed with clearance for aftermarket head studs, making it an excellent choice for performance-oriented Cummins builds where upgraded cylinder-head fastening hardware is being used. Time-Sert Mounting System Integrated Time-Serts provide durable threaded mounting points within the billet rocker box. This design helps provide reliable thread engagement while allowing the rocker box to be securely fastened to the engine.
