MOOG K400018 Idler Arm 11-19 GM 6.6L Duramax
Description
The idler arm on your Duramax is designed to connect your center link to the frame, essentially bracing your steering to a non-moving part. Because of this, a worn idler arm will lead to your truck wandering or wobbling and even harsh vibrations that will be felt right in the steering wheel.
Replace the failed or failing Idler Arm in your Duramax with this Problem Solver Idler Arm from MOOG that features a greasable socket design for reduced corrosion and wear along with a one piece design means its a longer lasting unit compared to the stock idler arm.
