HELI A21B4-30001 Rear Axle Assembly
The A21B4-30001 axle assembly is the OEM HELI rear steering axle assembly — the complete rear axle unit including the axle beam, steering knuckles, kingpins, wheel hubs, and steering cylinder mounting — for HELI forklifts equipped with the A21B4-30001 axle specification. The A21B4 prefix identifies this as a HELI factory axle part number. As a complete assembly rather than a bare beam, the A21B4-30001 axle assembly replaces the entire rear axle in one unit, making it the correct replacement when multiple axle components have failed simultaneously or the axle beam has suffered structural damage.
Built to the HELI A21B4-30001 OEM specification, this axle assembly includes the axle beam with forged kingpin mounts, pre-installed kingpins and bearings, steering knuckles, wheel hubs, and the steering cylinder mounting bracket at the OEM center position. For individual steering knuckles, kingpin kits, and steering cylinders, browse our forklift hydraulic components.
