2" coupler to 2 5/8

My 1966 AS has a 2" ball on the weight distributing hitch end, and I wonder what I need to do to fit a 2 5/8? I know I can change the ball but what of the coupler side?
It tows fine, just thinking it would be better with the larger ball set up.

A 2 5/16 coupler is needed for the new ball.

ALANSD,

The 2" ball has worked well for over 45 years, I say keep it. I think you will also find it is made with better metal than anything you can replace it with today anyway.

I've pulled my 1966 Overlander from FL to MO to NH with never a problem using the original 2".

This Is No Arbitrary Modification...

... as Paul has already suggested, you should just let it be, unless you see some cracking or other indications of metal fatigue.
But if you must remove and replace the coupler, it would be good to upgrade to 2 5/16"
Make sure you are dealing with a certified welder as it involves cutting the old coupler off and welding the new one on.

I changed a trailer coupler from 2 inch to 2 5/16 many years ago. There is nothing wrong with the 2 inch coupler. I did it so that the two trailers I had would be compatible.
Now I just keep 2 different heads around. I would not change it again unless I was replacing a defective coupler. Then I would go 2 5/16 for better compatibility with todays trailers.
I did build a utility trailer with 2 5/16 because a lot fewer people will try to borrow it
