Industrial 2530-01-420-3839 Steering Idler Arm

AM General's Steering Idler Arm for the Humvee family (NSN 2530-01-420-3839), part number 12460467 (alternate 6004839), is a front-position steering linkage component designed to support the center link and preserve steering geometry during military, tactical, and off-road operation. Built as a heavy-duty forged-steel piece with a corrosion-resistant finish, it is frame-mounted with a pivot assembly to provide the pivotal connection for the steering linkage opposite the steering gear. It is commonly installed in AM General HMMWV variants including M998A2, M1025A2, M1038A2, M1097A2, M1114, and Hummer H1, delivering reliable steering response when navigating rugged terrain or undergoing heavy-duty service. Typical applications include steering system repairs, replacement of worn linkage components, suspension overhauls, and restoration of tactical vehicles. For compatibility, this idler arm corresponds with the AM General 6004839 reference and is listed among common replacements such as the Hummer H1 Steering Idler Arm Assembly.
