I installed these on my truck in back in July of 2016. The ride height and quality was the same as the factory springs. These springs along with the AirLift bags do a great job of keeping the truck level when fully loaded to the trucks max capacity. Easy install and highly recommend for those who tow a lot and still want the factory ride and height when not towing.
