2011-2024 Duramax Idler Pivot Assembly Forged (158040111)

Fits

A broken idler arm pivot assembly can cause steering to feel loose and sloppy, and can even lead to premature wear of your tires and steering linkage. This more profound for lifted trucks with bigger wheels and tires.The PPE Forged Idler Arm Assembly is precision-built to handle the stresses of larger tires, off-road driving, drag racing and towing.

Fitted inside the forged steel housing are two tapered high-load roller bearings with rubber seals to protect them from water and debris. The heavy-duty dual roller bearings are pre-greased. If you spend a lot of time with your axles under water, we recommend a periodic re-grease using the built-in zerk fitting. For normal use (including off road, high mileage, heavy-duty), the PPE Forged PPE Idler Arm Assembly requires no maintenance.
