After going to my local Spring shop (which is quite big by the way) and getting an $800 estimate to add 2 springs to my 2012 F350, I am thinking about supersprings. Are they a DIY project ?
Never dealt with SuperSprings, but I put a set of Roadmaster Active Suspension on our E-350 van, and it wasn't too bad - would have been a piece of cake on a lift ......
