If you think you know there are differences....you don't really know much of anything.
The control arms are exactly the same as every other TJ model.
The springs are exactly the same as many other TJ/LJ models. Spring depends on the weight the jeep was ordered with. hard top vs soft top, Rubicon vs Sport (heavier t-case), manual vs automatic (heavier tranny), 4-cyl vs 6-cyl (heavier engine), etc.
As stated, the Rubicon springs won't give you any lift, they'll only return your jeep to its originaly height if your current springs are sagging and worn due to age/mileage.
The primary differences between the Rubicon and any other TJ model is the NVG2401OR t-case and D44's front/rear with air lockers & 4.10s.
