Product Summary

The Ultra-Tow XTP Ultra-Pack Trailer Hub comes fully assembled and prelubed with a proprietary grease-through system that allows complete bearing repacking without hub removal. Fresh grease is injected through the zerk fitting and flows through both inner and outer bearings, purging old grease out the front to protect the rear seal and simplify maintenance. A triple-lip spring-loaded seal helps guard against corrosion while the electro-plated finish resists rust for long service life. Designed to work with an existing spindle for quick installation.
