I have an Overland - but here's my results -
The max tow rear springs are SHORTER than the stock Overland rear springs. It was a lot easier putting the shorter max tow springs in the rear than getting the longer Overland springs out.
The end result at the back - mine dropped about 1/8" of an inch. Likely it sat nearly the same because the max tow is made to hold more weight and not "sag" while the softer Overland springs settled more with the same weight.
The result for rear springs - a bit harsher ride in the rear. It was definitely a softer ride with the stock Overland springs. However, I can toss a thousand pounds in the back and it doesn't settle nearly as much.
For the front - I put the softer of the Rubicon numbered springs under the front of my truck. The Rubicon springs were a bit longer, not a lot. I gained about an inch, maybe a bit less. I'll say on the low side of 1" with the spring swap. Ride is nearly the same. Maybe not QUITE as soft as the Overland but up front hard to really tell the difference.
All this means that the front of my truck went up a bit and the rear stayed about the same. That's the result I was hoping. There's still a lot of rack to the truck.
Since a lot of the Rubicon weight difference is in the WIDER axles, the TIRES (although I've not directly compared the weight of the stock A/T tires with the stock Overand H/T tires, they sure seemed and felt heavier when loading and unloading them from the back of the truck.
You have the weight of the Rubicon sway bar with disconnect system which is sprung weight. Doesn't the Rubicon even with plastic bumper also come with a steel skid plate? So there's skid plate weight (not a feather for sure)
So yes there's unsprung weight differences, but also sprung weight in the skid plate, the sway bar system, whatever else about the Rubicon is different - is the hood any heavier at all?
In any case, swapping springs on an Overland - max tow on the rear - almost a wash with the Overland. Fronts - the Rubicon springs raised my truck about 1"
Stock overland has a pretty cushy ride.
