The Rubi suspension does not add any height to the vehicle. The difference comes with the diameter of the tires from the factory which give about 1 1/2" of lift compared to a similarly equipped Sahara. I checked this out with a co-worker's Sahara parked beside my Rubi, and it is also noted on the spec sheet in the Jeep Wrangler pamphlet from the dealer. The Rubi springs are also a little stiffer giving a slightly harsher ride.
