I bought the 3" lift from Jason. When I first installed it, I was thrilled to death. After awhile, it got to be really rough ridin'. Come to find out, the shocks were bad and I got new ones from Jason. As was said, he's a great dude and they will take care of you, no problems at all. I had the new shocks on for a month or so and now it rides like a log wagon again. I am resigned to the fact that the shocks just are not good quality and I will have to buy some that will last more than a month without wearing out. I drive alot of gravel roads, and I can't see it hurting them that bad, but I'm sure if I take them off they won't even uncompress.
Bottom line is, the springs and custer service are second to none, but the shocks that come with the lift aren't any good, or at least the ones I've had weren't.
