Power Driven Diesel’s Batwing Rocker Pedestals for 1989–1998 5.9L 12v Cummins engines are a serious upgrade for anyone chasing better valvetrain stability, improved lubrication, and serious durability.
This complete set of six stainless steel rocker pedestals is proudly made in the USA and built to handle everything from a reliable daily driver to a 2,000+ horsepower race truck. Each pedestal is precision cast from 416 stainless steel, heat-treated, and CNC machined for a perfect fit. The “batwing” design features a nearly 90% wider base compared to stock, drastically reducing rocking and deflection under load. That means more stability in high-RPM or high-horsepower applications, and less wear over time. They’re also pre-machined for head stud clearance and come equipped with Power Driven Diesel’s Max-Lube pins, hardened chromoly pins with custom oil grooves that increase lubrication across the rocker’s surface to prevent galling, even under heavy stress.
These pedestals are a solid foundation for your valvetrain, no matter how far you're pushing your Cummins.
