Great kit from a great company with outstanding customer service. I was lucky enough to do a side by side comparison of zone and rough country and the Zone suspension was the winner hands down. On road the zone was a much nicer all around ride and was in no way jarring like RC. I have had the suspension on for 1.5 years and aside from re-torqueing once after a few hundred miles and regularly greasing it I have had no problems. Offroad the kit performs very well and has handled plenty of abuse and flexes great with the sway bar disconnected. I have installed the kit on my 06 rubi, 285/75/16's on moabs and at full lock they rub the lca's. I was fortunate enough to skip the t-case drop and have no vibes due mainly to the fixed yoke on mine. Before I installed the kit I made sure to clear coat the shocks and damper with several coatings of rattle can clear and after an Iowa winter(salt) they are rust free and look like new. I added a 1.25 spacer to the front to compensate for my winch. I am very happy with this kit.
