I would look at the eibach and OME kits. They are really similar the OME is not adjustable the Eibach is and they have something in the works for rear springs I think. The only reason I went with OME is free shipping, and in some of the pics the Eibach lifts the front looked higher than the rear. It could have been the angle but once this OME suspension is done I will be going Eibach or toytec boss or Ultimate. But just starting out check out the Eibach thread. Here is 43 pages for your reading enjoyment. Ryan is great also he will answer you withing hours. I literally went though every lift thread I could find and read as much as I could since January when I bout the 4Runner, I finally bought the lift 2 days ago.
