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 ?
See man, I knew I shouldn't have clicked on this email, I had to go see what you were talking about and ended up buying a set of Timbrens for my old 12 valve. :)
