Can Trailer Coupler for 3 Inch Wide Tongue Fit 2 Inch Wide Trailer Tongue

Question

Question:

Can I put a 3 inch channel, straight tongue trailer coupler on a 2 inch channel? I’ve been looking to upgrade my coupler to a Bulldog, collar-lok coupler. However, I can’t one to fit. Thanks!

Usually you want to have a coupler that fits the exact channel size on your trailer tongue but you should still be able to get a coupler designed for a 3" channel, like the Bulldog Collar-Lok Coupler w/ Pin # BD028244, to fit your 2" trailer tongue by welding on some shims to take up the extra 1/2" on either side of your tongue. I recommend having a professional welder do this for you so they will know how to get the welds exactly right for this type of application.
