Hitch ball size

[Dave176]

we are looking to purchase a Rockwood 2706WS ultra
lite trailer. does anyone know what the ball size is on the coupler?
just checking to see if will need a new one. currently have a 2"

You’ll need a weight distributing hitch with a 2-5/16” ball and bars with the correct weight rating.

I’m pretty sure 2 5/8” will be what you need. That’s what I have for my 2703WS.

i currently have a WDH with a 12,000lbs tow capacity & 1200lbs tongue with a 2" ball
will need to buy a new WDH which take the larger size ball? or can still use the one i have by just changing the ball size?

I don’t see how that hitch of yours could have a 2” ball, they don’t have that much weight capacity. If you already have a WDH then the ball should be 2-5/16”.

our old trailer was about 4000lbs and it required a 2" ball.
so my setup should be able to accommodate the larger ball size?
i was wasn't sure if the hole would fit the larger ball do to the thread size.
unless all the thread sizes are the same?

There are different ball thread sizes so you’ll need to remove the ball you have and measure the size of the hole but a 2-5/16” ball should be pretty standard in that way.

Purchase a new ball but, make sure it is a quality ball with a large shank. Some come with small shanks and an adapter sleeve to fit the hole in the receiver. The highest rating stamped on the top is what you're looking for.

She thinks it’s 2 5/8”. Don’t tell her otherwise.

finally got the old ball off, and have confirmed i need a 2 5/16 ball.
hole has plenty of room for the larger ball size.
thanks to everyone for your help.

"Plenty of room" is not what you want. Exact fit shank to hole is what is needed. Otherwise the ball will move around in the hole, and eventually something will give.

[Dave176]

Sorry all I meant was the hole would accommodate the larger ball size.
Yes I will be getting the correct shank size.
