10K General Duty Hub + Bearing, Seal & Oil Cap Service Kit – Lippert
Part Number – 183168-KIT
This 10,000-lb General Duty (GD) hub service kit is built around the Lippert 183168 idler hub and provides every key component needed to replace the hub-side assembly on post-2009 GD axles. The verified bearing stack includes 25580/25520 for the outer set and 387A/382A for the inner set, paired with the correct 10-51 oil seal (10-2875-08) and the complete oil-cap assembly used on Dexter and Lippert GD axles.
The 21-88 threaded aluminum cap, matching O-ring, and center fill plug are OEM-spec components that maintain the factory seal and lubrication system found on 10K General Duty axles. Each kit is packaged for precision service and reliability on heavy-duty flatbed, equipment, and lowboy trailers.
Note: Outer and inner bearing races (25520 / 382A) come factory-installed in the Lippert 183168 hub. Bearings, seal, and cap components are supplied separately for final assembly.
This kit services the hub side only. The matching 183537 brake drum is sold separately. For backing plates, magnets, and full GD running-gear support, see our 10K Parts Collection.
