I Bought and installed the "Suspension Maxx" front kit. I'm very pleased. It installed very nice in about 4 hours. The instructions weren't the best but adequate Quality parts. I decided to do just the front. I like the level look it has now without raising the back. next.... rims and tires!! I'm going to go with 17" or bigger because I know I'm going to go with the spindles some day too. Any comments on where to get a great deal on tires and wheels? Thanks for all the info from everyone.
