Spring Choice: We used the 43-1849 two leaf 2011-16 F250 springs in developing this kit. They are the softest rear spring you can get. If you are towing or hauling you will either want to add air bags to these, or run a stiffer spring.
The 43-1705 spring is the three leaf pack used in 2008-16 F250 / F350 SRW / DRW trucks. Very common. It's a 3600 lb. spring which is equivalent to stock OBS F350 rear springs. It also sits about 1.5-2" taller than the spring this kit was measured with. Lift springs seem to be measured off of these springs not the 2 leaf.
The kit includes our 2" or 4" rear flip brackets, The front hanger is the same for both.
You need the whole kit to complete the swap and keep the correct suspension geometry. We only made the front hanger only an option for those that already have the 2" or 4" shackle flip and/or boomerang shackle.
E-brake bracket is intended to be bolted or welded on to match your specific application, We have found there is enough variance in location from one chassis to another that it doesn't allow us to place the bracket for you. Hangers have 2 pilot holes in case you want to drill larger holes and run bolts in a location you choose. Powder coated kits will require drilling and tapping to locate e-brake bracket.
If you have a standard cab truck you will have to slide the front tank over to be able to get behind the frame to drill the necessary holes and install bracket. We installed this kit on a single cab truck, it is possible without removing fluid lines off of the inside of the frame.
