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.
