UNSPSC 25174216: Steering knuckle arm

Part of a forging that usually includes the steering knuckle, spindle and steering arm, and allows the front wheel to pivot.

UNSPSC 25174216 Steering knuckle arm is a Commodity code that captures individual vehicle suspension and steering components sold as replacement parts and subassemblies. State and local governments purchase steering knuckle arms primarily through fleet maintenance and repair contracts for buses, trucks, and other operating vehicles. The issuing bodies soliciting under this code span school districts, transit authorities, and counties — organizations that maintain substantial vehicle fleets and source OEM and aftermarket replacement parts through blanket purchase orders and standing distributor agreements. Work solicited includes supply of new OEM steering knuckle arms to fleet service centers and repair facilities, often bundled with broader bus and vehicle parts packages where parts are ordered on an as-needed basis throughout a contract term.

Recent state and local opportunities show limited direct solicitation specifically for steering knuckle arms as a standalone line item. Parkway School District in Missouri posted RFB 26120 in May 2026, seeking OEM replacement parts and service for its bus fleet under a blanket purchase order with a response date of May 19, 2026; the solicitation encompassed a broad range of suspension, drivetrain, and structural components typical of school bus maintenance. The Williamson County Purchasing Department posting and the Sourcewell law-enforcement-equipment RFP in May 2026 do not support steering knuckle arm procurement. Missouri and the broader Midwest region show active fleet maintenance procurement activity; however, steering knuckle arms are typically purchased as part of larger OEM parts packages rather than solicited as discrete commodity line items, making direct pursue opportunities under this Commodity code sparse in recent state and local postings.
