Buying Guide
What matters most when selecting aluminum trailer components? Consider rust resistance, weight, and compatibility with your trailer’s frame and hull. Aluminum fenders and mounts should match the fender type (round vs square) and bolt patterns. Guide poles should fit your trailer’s crossmember dimensions and provide enough height to assist loading. For tires and rims, look for DOT-approved assemblies with the correct bolt pattern and bore size, and verify the load rating aligns with your trailer’s weight.
