Question:
Good morning I have an aluminum utility trailer and I need to replace the coupler. It is a 7000 pound dual axel trailer using a 2 5/16 ball. What coupler would be a suitable replacement and not cause galvanic corrosion.

Expert Reply:
Hello Matthew, if I were you, I'd go with a coupler that has a strong powder coat finish, which is typically the best route to go for corrosion-resistance. The Demco 50-Degree A-Frame Trailer Coupler w/ Jack Hole and Anchors, eZ-Latch - 2-5/16" Ball - 21K # DM16680-52 is a great option. It can be bolted on or welded on (in your case bolted on since aluminum and steel don't play nicely when welding), and it has a really nice "eZ-Latch" which is super user friendly. It also has a strong silver powder coat with a salt spray rating of 500 hours which is higher than most.
Let me know what you think; hope this helps you get the trailer back on the road again!
