With todays JKs getting bigger, heavier and providing more horsepower to spin 37s + a 1 Ton Swap is undeniable. Luckily, we have made it as easy possible to put a giant axle not meant for the vehicle you are trying to put it in. It is expensive. However, it is worth every penny if you are planning on keeping your vehicle forever or if you really just want to wheel it. DO IT!
There is the easy way and the hard way, these packages are the easy way. Hard way, buy used axles, shave them down to bare tubes, weld control arm mounts, shock mounts, track bar mounts, rebuild them hope they are not bent.
