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
