With 37" tires it won't shift to 8th gear...can't get mine to do it..if you want 8th back..you will have to Physically change the gears in the axles to a lower number..like 4:88 or 5:13.Make sence
Getting that much closer to getting the JT lifted and 37's on her...just got the wheels mounted and balanced..and rock rock rings installed..now just need tuner and money for install
Lol..this shis is expensive.
