Where are they measuring the ground clearance? At the skid plates? Clamshell differential? Or the actual lowest part of the vehicle ie the LCA? Because actual ground clearance would be the same regardless of suspension since tire height is the only thing that actually increases the clearance at the control arms. Manufactures do this kind of misdirection a lot, Toyota did it with the 3rd gen 4Runner claiming ridiculous 15" of ground clearance but the actual ground clearance is around 10". They measured and advertised the clearance at the front clamshell differential and not the actual lowest point which was the rear lower control arms and shock mounts since they hang down below the axle.
They did that so they could say it had higher ground clearance than Jeep Wrangler.
He's an angel dressed in oilskins; he's a saint in the "Sou'wester,"
He's a pluck as they come, or ever can;
He's a hero born and bred, but it hasn't swelled his head,
For he's just the U.S. Government's hired man.
