Complete 10,000 lb rated oil-bath hub and drum assembly designed for Dexter and Lippert 10K short-spindle axles. Fits 12-1/4" × 3-3/8" electric or hydraulic brake assemblies and includes bearings, races (pre-installed), oil seal, aluminum oil cap, and eight 5/8"-18 lug nuts.
Intended for oil-bath configurations using short 10K spindles. Not compatible with long-spindle or grease-type hubs.
Oil-bath hub systems use gear oil rather than grease to lubricate bearings, allowing improved cooling and easier visual inspection through a clear oil cap. Short-spindle 10K axles use specific inner and outer bearing combinations and seal dimensions that differ from long-spindle or grease-type hubs.
Proper fitment depends on confirming spindle length, bearing numbers, seal size, and brake dimensions. Always verify axle type and specifications before installation.
