thedirtman and ALASHA are on point.
I have the Teraflex kit, but I bought it to replace a normal ( short/mid arm ) on a JKU - solely for on-street reasons and since i had to do an arm replacement and mount repair otherwise anyways. If you do get the Teraflex kit, get the Nemesis slider for the lower mount nt just to slide but reinforce.
( I couldn't get the Synergy in stock by when I wanted to install, and I was getting the work done through a shop that doesn't sell EVO.)
