I put these on the F350. Between gathering the tools and installing the airbags, the installation took about 6 hours. Left the wheels but had to remove the shocks to gain access. It's not that hard, but if you do these things you'll be fine. I am happy with the performance. I tow a backhoe trailer 10km and put 30psi pressure in the bags to level the truck. It's easy to equalize the pressure in two bags.
