I know at this point others have installed this suspension as well so hopefully we can get a few people to chime in on this. I've had this lift for a little over 2yrs now with no real complaints. I had a hell of squeak in the beginning but once the weight of the bumper was installed it subsided. That said, all lifts rattle and squeak so not a real complaint. The powdercoat/paint on the leaf springs is pretty weak. It's all surface rust but it is pretty mucked up under there. Again, not a real complaint, only a quality statement.
The ride has held up tremendously, flexes well on the trail, and has driven across the country now six times. At the price point it is definitely a contender in my mind as an entry level, daily driver, all around lift kit.
