I cannot say, I know that the early 95-97 Limited's did set lower than regular trucks. I test drove a 95 Limited with 21k on it in 1998, and noticed the much softer ride and lower ride height.
I have learned that the fenders are not mounted evenly on the trucks, they should all measure higher on one side than the other.
The frame is the baseline, and the suspension needs to be level to provide even handling. If you jack up one side to make the fenders level, then the handling will be different turning left versus right, like NASCAR does on purpose.
I measured my Mountaineer and Explorer by the LCA front mounting bolts. My Explorer wouldn't lower anywhere near as far down as my Mountaineer is, they are about 2" different. I think my Merc is about 8.5" from the ground to the center of those bolts. My Explorer is probably around 10.5" there.
The ride quality changes quite a bit at different ride heights, as does the handling. Make it as low as you can for handling and safety, but the ride gets rougher as you do to.
To lower the height of an ARC vehicle is difficult, most people can't understand how it's done properly. The ARC wants a specific height, and any normal changes made with torsion key adjustments don't affect the ARC decisions. The ARC will add air to achieve its height, and let out air to get there, as needed.
To lower an ARC vehicle requires a change to both the height sensors and the vehicle(normal methods). I lowered the back of my 99 ARC Explorer by about an inch or so. I used 1.5" lowering blocks, plus altered the rear height sensor mounting point. So the final height is 1.5" down, plus a little up from the ARC system. If I had not changed the ARC height sensor, the ARC would have added air to regain the original height. If I altered it to go below the 1.5" amount, then the ARC would let all of the air out of the shocks(attempting to drop it below the 1.5"). In one case that would achieve no height change, but pump up the shocks too much. The other case would result in shocks without any air, which is also bad for the shocks.
So if you do want to alter the ride height, plan it carefully. You need to be sure that the ARC shocks always have some air in them, the ride height should be in the middle of its sensor range(not above or below the limits). That means that the sensor length has to be changed to allow the ARC system to be wanting the height you set mechanically.
