Is Ground Clearance by the manufacturer wrong?

[DrJeep]

So much confusion and incorrect interpretations of how much taller is Rubicon/Mohave compared to sport and if swapping suspension components gives any additional lift/ground clearance and what is every model ground clearance, etc.

Jeep claims that non-Rubicon models' ground clearance is 10", Rubicon is 11.1" and Mojave is 11.6". Have you ever wondered why Rubicon and Mojave have different ground clearance despite having the same axles and on the same size tire (33")? Many also assume Rubicon is 1 inch above Sport/Overland because its tires are 1" larger in radius - wrong. Rubicon's driver seat is about 2.1" higher than Sport's. (1" from tires, 1.1" from suspension)

Well, the truth is that Jeep actually means running ground clearance which is defined as the lowest point of the sprung components to the flat ground and that excludes rear/front axles that are unsprung mass. In fact, Rubicon and Mojave axles are only about 10-1/4" above the ground, and sport is about 9-7/16".

So, based on factory data, it is evident that Rubicon is sitting 2.1" higher than Sport due to its suspension and tires and Mojave is 0.5" taller than Rubicon. The true ground clearance is only set by the tire size given that the lowest point is the differential. Here is a picture of my Sport on 35" which is (34" under load). Note that it has given almost 1.5" extra ground clearance compared to 31" stock tires, (34-31)/2=1.5".

Pro-tip... get a binder clip and something like a credit card and clip it to the measure side. Put it on the ground, take tape measure off, and read actual distance.

This clip wasnt too strong but you get the idea.

The definition in that link is not right. Running ground clearance, as used by Jeep, is the lowest point of sprung components. That is, components that are "on" the suspension and supported by it and this excludes axles.
