Unitized Oil Seal for DX 9-10K GD Axles

Unitized oil seal for Dexter 9K-10K general duty trailer axles. This premium replacement seal (part 010-51) features a dual-action design that stays fixed on the spindle while the outer casing rotates with the hub, minimizing wear and preventing oil leaks. Compatible with 9,000-10,000 lb axles, it provides superior sealing for oil bath hubs on utility trailers, boat trailers, and cargo haulers. Easy to install and built for long-lasting performance in demanding towing conditions.
