      There are a few options. What year is your Wrangler? Older ones have a speedometer gear that you can change. Its really easy to change. If your TJ is newer and you don’t have the speedometer gear (tone ring setup) you can get a speedometer recalibration device. I will be using one made by SuperLift called the TruSpeed.

          Someone please correct me if I am wrong, but you will have do something along the lines of the TrueSpeed then since your TJ uses the electronic tone ring. There is a cheaper solution then the TrueSpeed, but I cant remember the name of it at the moment.

            No, only the Rubicon model needs either a dealer re-program or a tru-speed. All other TJ's with the 231 T-case can do a speedo gear swap.

              Did you install a sye and cv? The Teraflex ESS and JB use a tone ring and requires an electronic speed converter. If you use a regular sye then just use the right speedo gear for your gearing and tire size.

              With a 6" lift, don't tell us you don't have a sye!

              What gearing and tire size?
