We do have plans for developing a long arm JK suspension kit, we are working on a few different concepts, but honestly our standard short-arm kit works very well for lifts up to 4.5". You can fit 37" tires on a 4" lift so I hardly see the need unless you are looking for 6"+ of lift. The suspenion companies that are pushing long arm kits are the ones that had great success with TJ long arm kits, they were needed to get 35's on a TJ, but not on a JK, they are just pushing you to buy more of their parts.
