24v Cummins – Trunnion

Manton 24v Cummins Trunnions

Introducing the Rocker Arm Bushing Repolishing Tool for HD Billet Tool Steel 24V Cummins Rocker Arm Trunnions.

OEM trunnions may fail under heavy load, causing rocker arm and pushrod issues.

Our heavy-duty trunnions feature larger oil supply holes and increased oil groove width.

They also include two additional oil transfer grooves for optimal lubrication.

CNC machined from premium tool steel, core hardened, precision ground, and nitrided.

This enhances durability and reduces friction, extending rocker arm and trunnion service life.

Each set includes a rocker arm refinishing kit for polishing the bushing surface.

Trunnions are in stock and ready to ship the same day you order!
