Base that I put more aggressive wheels/tires on. Rides a bit stiff (according to the wife!) but it hasn't gotten any harsher than it was with the stock steelies and minivan tires.
Check the tire pressure and maybe reduce a little bit- 2-3 PSI. I find that even a small change in PSI can make huge difference. I have a 2 door Basesquatch and it rides really nice. I reduced the Ford recommended tire pressure from 40 to 38 (checked cold). At 40 it was a little firm in my opinion. Tire wear is still even.
I've got a 2Dr Base 2.7 with auto. It rode just fine from 0-500 miles with stock tires, and now that I've put OBX wheels & tires on it (32s) it still runs fine with about 2800 miles on it.. No problems, and no jerks or bumps. I run 37 pounds in the tires.
I had a 2016 75th Anniversary Jeep Wrangler 2Door before this. Bronco rides better than that one did, but then I didn't mind that one either (no death wobble).
Go take a new one for a ride at your friendly dealer to compare. If its vastly different then take yours in and have it checked out.
