Hi everyone, so I recently bought a new tj(totaled my first one so I naturally had to get another). As it sits, it’s got stock axles running 35” tires on a 4” lift(all professionally installed). It’s the inline 6 5 speed manual, and currently, on the highway unless it’s a straight away 5th is a dog. In fourth, hills and anything are no problem doing 65-75mph @2200-2500rpms. So what would the best gears to do a swap? If any?
