I have not had the shocks on very long abought 200 miles on them but they make the truck ride and handle a lot better.My Truck is a 2001 Dodge Ram 1500 4X4.The only problem I have had with them was the fit of the one of the shocks at the bottom were the bolt goes threw the shock.I had to grind the side of the shock bolt hole to get to fit in the shock cradle at the bottom on the front end of the truck.Other then that they look like a good quality heavy duty shock.
