My truck's rear springs were modified during the rebuild in a way that I did not authorize, so they have very little cushioning when going over a bump or hitting a pothole. So when I get back from KC I plan on taking it to a spring shop about 50 miles away to have it fixed, I would like to have the rear end raised 1 inch in the process. The springs are not original because the rear end is out of a 79 Chevy Nova and was custom made for it.
