Power Driven Doweled Batwing Rocker Pedestals — 1989–1998 5.9L 12v Cummins
Rocker pedestal failure is one of the most common valvetrain issues on a modified 12v Cummins. Aftermarket valve springs, aggressive camshafts, and even prolonged stock use cause the factory pedestals to walk, rock, and deflect — leading to accelerated wear and eventual valvetrain damage. The Power Driven Doweled Batwing Rocker Pedestal solves this at the root: a stabilizing dowel on the small end engages a mating bore in the cylinder head, physically preventing the pedestal from walking under load.
These are 100% American-made, precision cast from 416 stainless steel — nearly 3x stronger than OEM pedestal material — then heat-treated and CNC machined. The nearly 90% wider base footprint dramatically reduces pedestal rocking and deflection, and each pedestal is fitted with a Power Driven Max-Lube Pin for enhanced lubrication at the rocker arm wear surface.
Features
- Stabilizing dowel — Engages mating bore in cylinder head to prevent pedestal walking under load from aftermarket springs, cams, or extended use
- 416 stainless steel — Heat-treated and CNC machined; ~3x stronger than OEM material
- ~90% wider base footprint — Reduces pedestal rocking and deflection
- Max-Lube Pin — Hardened chromoly, centerless-ground, with enhanced lubrication grooves to increase oil flow across the rocker arm wear surface and reduce galling
- Head stud clearance step — Innovative radius reduces stress concentration; compatible with factory or PDD upgraded head bolts (hardened washer may be required under bolt head)
- 100% American made
Kit Includes
- 6x doweled batwing rocker pedestals with Max-Lube pins, pre-machined for head studs
Fits
- 1989–1998 Dodge Ram 5.9L 12v Cummins
- Suitable for stock through 2,000+ HP race engines
- Requires Power Driven Ported Cylinder Head manufactured after September 1st, 2023
