Trailer Hub 3.5K Capacity – 5-Lug Idler Hub
Description:
This 3,500 lb trailer idler hub assembly comes pre-greased and ready to install — no messy bearing packing required.
Built for 84 spindles and compatible with nearly all major 3.5K trailer axle brands, this hub fits trailers using 5 on 4.5″ or 5 on 5″ bolt patterns.
The hub includes all internal components — bearings, races, seal, grease cap, and lug nuts — pre-installed and lubricated with lithium-complex multipurpose grease for long-term protection. Its cast-iron body and zinc-enriched paint coating help resist corrosion while maintaining excellent heat dissipation under load.
