Approximately 35k miles on it, includes springs and extended shocks. In the spirit of full disclosure, Bushings have some dry rot and the flats are a bit knackered from when I tried to remove without air tools. Also, as the previous owner installed them I am unsure if they are medium or heavy duty. The truck did have a winch bumper with no winch and it sat perfectly level so not sure what that indicates. Priced at 250 plus shipping and located in NY
