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 ?
Yes it is a DIY project. They make it so you can remove the spring pack when you're not using it and install it when you need it. I have the two leaf springs installed and it has worked out fine for me. It is a bit heavy to remove and install so I would suggest talking to them directly. They've helped me out in the past and give great support.
