New hd has the class5 receiver with a 2.5 inch opening. I have been using the Equalizer 10k hitch that is 2". I have purchased a reducer that converts from 2.5" to 2".
TT hitch wt is 800lbs and 7500 gvw.
Is there any changes needed? Equalizer 10k still good?
Be warned, if your new unit is a Ford, there may be some issues with some of the reducers sold. The problem is the Ford units are slightly different then some third party units.
If you have a Ford and run into this problem, do NOT grind anything off, your options are to exchange it or try taking the paint off. I managed just fine by taking the paint off.

Other then the loaded hitch height, nothing is different. The rear squat (rear spring rate) is likely different, so teh loaded height is all that matters. Adjust the hitch so the front end is at the same height - or slightly lower then unloaded.
The owners manual for my '11 does not mention anything about the capacities being reduced when using the reducer. You should be just fine, just don't forget to take it out when you take your hitch out of the receiver. I have almost forgot on several occasions.
All I had to do was adjust the hitch head height a bit as the 2500HD sits higher than our previous tow vehicle (4Runner), and add a spacer washer as the truck is much longer wheelbase. The only thing I didn't care for, but it still worked fine, was how sloppy the reducer sits in the hitch receiver. My new heavier Equal-i-zer for my soon to arrive heavier trailer will have a 2 1/2" shank to fit better in the receiver, as I had to order a special size shank anyway.

The reducers can be a pain when sliding the hitch in as now you have to line up two sets of holes for your pin. If you aren't ever going to use a 2.5 hitch, you can just tack weld the reducer sleeve in place. I added a 2.5 Reese Titan to my 09 F250 as my Arctic Fox had a Reese Dual Cam setup with a 2.5 hitch. When I sold it for our last trailer, I went to an Equalizer as they are MUCH easier to set up and hook up. It only had a 2" hitch so I tacked the sleeve in place. All was fine in 2500 miles last year...
