I had my SS A10 medium duty Super Springs installed on my 2010 v10 F250 by my mechanic. Took about an hour to install. We did take off the tires to make easier. We put the setting in the middle hole. Ride is a little stiffer especially over uneven roads. But the truck now corners better. I have not towed with these yet.
Put a spring into my step!
I am amazed at how well these Super Springs work. They brought my pickup back up to the height it was when it was empty. Figured it would stiffen up the ride. If anything it rides nicer now. I have shown them to many of my customers. Some of the guys I talk to have had air bags like I had on my old pickup. I tell them these will be much better. I am very happy. Thanks Lonnie
