Buying Guide
What should you consider when choosing sealed boat trailer hubs?
- Spindle type: Determine if your trailer uses straight spindles or tapered spindles. Some hubs are specifically designed for straight spindles and are not compatible with tapered spindles.
- Bolt pattern and weight rating: Ensure the bolt pattern (such as 4×4″ or 5×4.5″) matches your hubs, and confirm the weight rating aligns with your axle capacity (2000 lb, 3500 lb, etc.).
- Prelubrication and bearings: Pre-installed bearings like L44643/L44649 simplify installation. Check whether seals are included and their sizes.
- Packaging and transport: Anti-collision, multi-box packaging protects parts during shipping and storage. Consider this if you move or store hubs before installation.
- Corrosion resistance: For marine environments, galvanized or cast iron with protective coatings increases longevity.
