Care information

To ensure optimal performance and extend the service life of your new trailer components, please follow these care guidelines after purchase:

  • Before installation, check all parts for shipping damage or missing components. Do not install damaged parts.
  • Always use correct tools and torque settings. Improper installation can lead to premature wear or failure.
  • For bearings, suspensions, and brake components, apply high-quality trailer grease before first use if not pre-greased.
  • Some parts (like brake assemblies) require a short break-in period to achieve full performance. Follow manufacturer instructions for best results.
  • Recheck fasteners, grease levels, and moving components after 100 miles of towing, then at regular intervals.
  • After exposure to water, road salt, or mud, clean and dry parts thoroughly. Apply anti-rust treatment if needed.
  • If storing unused parts, keep them in a dry, sealed container away from moisture and direct sunlight.

Product Description:

This trailer bearing kit for 6,000 - 7,000 lb axles include two complete bearing sets, making it an ideal all-in-one solution for servicing both hubs on a single trailer axle. Designed for dependable performance and easy maintenance, the kit contains OEM-matched bearings and compatible races that provide precise fitment, smooth operation, and long-lasting reliability under heavy towing conditions. 

Built with premium grade steel components and durable rubber seals, this kit helps protect your trailer hubs from wear and contamination. The double lip grease seals effectively block out water, dirt, and road debris to extend bearing life, while the 2.72" OD grease dust caps feature pre-installed EZ-lube rubber plugs that allow quick re-greasing without removing the hub. Spare plugs are also included for added convenience during long-term use and maintenance.

With two full bearing kits combined, this product offers a complete and convenient hub rebuild solution for trailers equipped with 6,000 -7,000 lb axles, helping ensure smooth rotation, reduced maintenance downtime, and safe, reliable towing performance.
