2015 F350 6.7 Crewcab Diesel 4x4. After installing this kit, the front will be approximately 3/8 inch lower than the back. I leveled it and didn't like the way it drove. I bought longer front shocks and installed them, but it still drove horribly. Offroad Shop and they pointed out that the front axle was biased towards the driver's side due to the stock non-adjustable cross member which was very small in diameter. $850 later, they added a large-diameter adjustable tie rod and re-centered the front end. Axle with new Pitman arm. Now the truck drives like new. $59 kit, $100 aligners, $600 shocks and $800 steering rack, bipod arm and axle adjust. By the way, a bipod arm was needed and my truck has put 37,000 miles on it. If you're towing heavy loads, plan for airbags as well.
