Jolly Green is close.
It leaves the upper control arms in their stock position, but does lower the lower control arms via a bracket. To compensate for the difference in height it uses different hub assemblys. For me, the advantage to this type of lift is that because the upper a arm stays stock position, you do not use a drop steering bracket, but retain all factory steering. I have fought death wobble on a few trucks that used a drop steering bracket and swore I would never do it again.
It does increase track width a little, but I am going to offset that by using H2 wheels down the road, which have more backspacing. In the end, it should be a wash. The kit comes with rear wheel spacers to compensate for the increased front track width, but I don't intend on using them. I'll just have to see where I am at after it is installed. Supposedly, this lift is a 4-6 and I really don't plan on going much over 4" and keep my CVs straight. I have never seen this kit on a truck before, but would be interested in other's opinions, first hand would be awesome. Please correct me if I am wrong with my info.
I was really close to pulling the trigger on a rough country because of the price, but chose to save a little more for this kit. I will check with him about it either way. Thanks all.
