Power Driven Doweled Batwing Rocker Pedestals

An evolution of our popular Batwing Cummins Rocker Pedestals, our all-new Doweled Batwing Rocker Pedestals feature a stabilizing dowel on the small end of the rocker pedestal. This dowel engages with a mating bore in the cylinder head to prevent the rocker pedestal from walking under load from aftermarket valve springs, aftermarket camshafts, or even prolonged engine use with stock components.

*Power Driven Diesel Doweled Batwing Rocker Pedestals are only compatible with Power Driven Diesel Ported 12v Cylinder Heads. All Power Driven Diesel Ported 12v Cylinder Heads come standard with the batwing dowel receiver bore.

Power Driven Diesel 12v Doweled Batwing Cummins Rocker Pedestals are 100% American made. Included is a set of 6 rocker towers/pedestals that are precision cast from 416 stainless steel. The rockers are also heat treated and CNC machined. These pedestals feature a nearly 90% wider base footprint to offer enhanced valve train stability by reducing pedestal rocking and deflection. This stainless alloy is nearly 3 times stronger than the OEM pedestal material and, working in conjunction with the wider base footprint, virtually eliminates pedestal deflection.

Each pedestal is carefully fitted with a Power Driven Diesel Max-Lube pin. Max-Lube pins are made here in America from hardened chromoly, centerless-ground to size, and featuring enhanced lubrication grooves. Max-Lube pins were developed to increase the hydrodynamic oil wedge at the pin-to-rocker arm wear surface by increasing oil flow across the width of the rocker arm to reduce the common galling issue at the rocker/pin rotating surface.

Power Driven Diesel Doweled Batwing Rocker Pedestals feature a step for head stud clearance with an innovative radius to reduce stress concentration. If using these pedestals with factory or Power Driven Diesel upgraded head bolts, you may need to add a hardened washer under the bolt head to ensure that the bolt does not run out of block thread engagement. Batwing rocker pedestals are suitable for both the mildest stock Cummins-powered trucks and the wildest 2,000 hp race engines.

Power Driven Diesel 12v Doweled Batwing Cummins Rocker Pedestals are compatible with Power Driven Diesel Ported Cylinder Heads (manufactured after September 1, 2023 in the following year range):
