If your planning on carrying extra weight (bullbar,winch,canopy etc)Have a look at king springs EHD. They will give you 20 to 75mm lift and are excellent quality. I paid $140 for the front and $700 for the rears. I'm using bilstein shocks, german quality,can be rebuilt, superb fade resistance. My next choice would have been the radflo's but there pretty pricey. In my opinion avoid the cheaper brands that are made in China. tough dog, ironman they just don't seem to last.
