The only Rubi feature replaced on mine was I re-geared for the 37” tires. Other than that I still use the Stock Rubi sway bar, lockers and such. So funds went to other areas faster for me with the Rubi model. I also got a great used deal on my Rubi not only on the vehicle but the PO had bought every aftermarket item available for the interior. So the savings in floor mats, grab handles, dash panels, cargo liners, gas cap cover and so on was pretty good too.
Local vehicle code is a good thing to check on as well, like just mentioned, but also conceder how close you want to push that compliance. My JK is legal….barely. Which will get me stopped for my size and my tire overhang sometimes even ticketed. I can print out the relevant documents
from my local .gov website but I still lose a day contesting the fine in court. And you will have to go to court even if the officer is wrong. You can’t prove that state trooper wrong to their face. It won’t go well, even with a tape measure.
