Recommend saving your money for other mods until you stabilizer fails. I ran my stock Jku without a stabilizer with minimal issues for a couple hundred miles because I started to install the Teraflex relocation bracket ( which is a decent mod to move the stabilizer up, put of harm' s way) and got pulled away to do something else.
