I was looking for something to firm up the rear of my half ton while towing. It was OK, but I wished for a little less sag and less sway when pulling our travel trailer. I looked at overload springs and air bags and finally Sumosprings. Autoanything had the best price and they arrived quickly. I had them on in two hours and hooked up my TT. Sure enough, I gained a little more than an inch to 1 1/4. I'm happy.
