Keep tight, predictable steering response on your heavy-duty truck with the MOOG K400018 Steering Idler Arm. It's a direct-fit replacement for the 2011-2024 Chevrolet Silverado 2500 HD, 2011-2024 Chevrolet Silverado 3500 HD, 2011-2024 GMC Sierra 2500 HD, and 2011-2024 GMC Sierra 3500 HD. The idler arm supports one end of the steering center link and works opposite the pitman arm to keep the steering linkage aligned; when it wears, you may notice steering play, wander, or premature tire wear.
- Heavy-duty design built for demanding chassis service.
- Engineered steel composition results in a stronger component.
- Powdered-metal gusher bearing design lets grease flow through the bearing.
- Greaseable socket reduces corrosion and wear by allowing new lubricant to flush contaminants.
MOOG has earned its reputation as the chassis industry's Problem Solver by introducing design enhancements that extend product life and simplify installation. Loose or worn chassis parts can lead to premature tire wear, so if a failed idler arm is the cause of your steering slop, this replaces it. See the Buyer's Guide tab for engine-level fitment details.
