Installed on a 04 Nissan Titan, and the change in ride quality was drastic. Much much better ride with these set at 50 PSI. Did raise the back of the truck a few inches, but worth it. Have not towed with these in place yet, but initial thoughts are that these are going to make a world of diffrence.
exactly what i needed
i was extremely satisfied with the quality of the parts in the kit. i expected them to be good and they were. i ended up wrapping all hoses with wire loom for extra protection. and i ran the hoses into the trunk. i used this in a ford fusion for a family of 4 trip totaling 2700 miles. the ride, once air was adjusted, was as good as stock. very smooth. if you over inflate, it will be extremely harsh and bouncy.
