The receiver is not weaker when using the sleeve. The tow rating is reduced because you are only using a 2" hitch. When you leave the sleeve out you can use the 2 1/2" hitch thus your capacity increases.
No. Equalizer rates both drawbars the same. The Ford limitation has NOTHING to do with the drawbar. That is why it makes no sense. And probably why the others don't have a separate rating as well.
Equalizer may rate both drawbars the same.
But a 2.5" sq drawbar has gotta be stronger than a 2" sq drawbar, all else being equal. So it does make some sense.
Not really. If I take my 2" draw bar that is rated for 18K, and put it in my GM 2.5" receiver, I get the same rating as if it was a 2.5" drawbar. It is only the Ford that rates it different... Ford doesn't rate drawbars, only their receivers. What they are saying is that their receiver is rated for less when a 2" drawbar is used. What makes no sense is that when using the adaptor, the load force will be the same. GM and I believe Dodge see it that way, and don't use separate ratings.
Another point, is that 2.5" doesn't have to be stronger than 2". It depends on the grade of steel used.
Yes, I see your point. Using higher strength steel, a 2" shank could be made as strong as a 2.5" shank. I guess your 18K 2" draw bar is one of them.
Perhaps Ford is ignoring all that and simply assuming that a 2" shank is not as strong and putting that assumption into its ratings.
Unless there's some other mechanical issue with using a reducing sleeve that may concern them. Other than the potential for wear and slop, I can't really think of one.
