My son-in-law has a TT which he tows utilizing a weight distribution set up. After installing the weight distribution, he experieced grinding of the TT hitch coupling on the top of the weight distribution ball platform during turns due to a lack of clearance. We have lowered the platform approx. 2" but still have a clearance problem with tight turns. This set up also allows for an angular adjustment.

I hope that I have stated the problem clearly. Any suggestions/solutions will be greatly appreciated.

If I understand your problem, a longer ball may help.

By a "longer ball" do you mean a ball with a longer neck? I can see where this would give greater clearance but, I'm not sure I have ever seen one.

concur with the neck thoughts - also sometimes refered to as the "shank".

If we are off base, a picture might help - if you have a side view of the hitch in question.

I had a problem with a utility trailer years ago. Borrowed the trailer, then discovered that I had a short shank trailer ball so it was unable to lock in.

As usual, the response has been extremely helpful. You'll got me to do some research which revealed the following:

A ball assembly has a "rise" and a "shank".

Has any one used a longer rise ball? The shank is that part with the thread and nut. Is there any problem with using large washers on the shank to raise the hight of the ball?

I wouldn't raise it with washers. Just get a longer one they aren't that expensive. Also when it has been tightened good, quite often the lock washer will damage the thread and make it unusable.

I agree with Cliff.

Do not use washers, as the shank may not be long enough, and I believe it will reduce the capacity of the hitch.

Modifying hitches is never a good idea.

So a longer rise is what is needed. I thank everyone for their informative responses

I tried to interest my Son-in-Law in IRV2 when he first got the trailer. Perhaps, when I relay this info. to him and the source, he will be more receptive.

The ball you are looking for is called a "Tall Ball" Just be sure to check the weight rating of the ball. DO NOT ADD WASHERS to your raise ball.
