Buying Guide
What should you check before buying? Start with spindle type (straight vs tapered) and axle capacity (2000 lb vs 3500 lb). Ensure the bolt pattern is 5×4.5″ and confirm bearing sizes (L44643/L44649 or L68149). Consider the material and coating (galvanized steel resists corrosion). Evaluate whether you need extra dust caps, seals, and spare hardware included in the kit for easier future maintenance. Clarify compatibility with your trailer brand (Dexter, Al-Ko, Lippert, etc.) and your spindle size to avoid mismatches.
