Care information
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.
