My buddy had a 7in skyjacker crap lift on his truck if i was you i would order some 2inch lift shackles too put on it or your stock ones will fold back and hit the frame and you have too use a prybar too get them unstuck! He had the 7 inch kit with new springs front and rear and that cleared a new set of 36 sx's pretty good especally in the mud but the only reason it would clear them was because it dont flex but maby 2 inches and it mad the truck way too tall and really easy too roll.
If you buy the 2 inch lift shackles there like 75 a set that will make it where you can clear 38's good especally if you only drive it on the street and mud it lightly. over time thow the lift will start too sag ALOT and will finally start flexing, he has the 7 inch springs up front 2 inch lift shackles and a 3 inch body lift and it clears 38 sx's pretty good they get into the back of the fender in a good flex but he has not beat it in with a sledge or cut it back any at all. and in the rear the springs when they started too flex finally they ended up bending into a small W shape and were
so we 3 linked the rear with cherokee front coil springs.
if you add a 3 inch body lift on top of the 7 inch sus 2 inch shackle you could maby clear 44's if your just driveing around town and dont flex it any with the wheels turned.
Have you thought about how the hell your going too power those 44's you wanted even with 5.71's your 22r will suck on power and wont like them at all even in low in the mud, if you wanna play in mud you have too have power and its just hard too get enought with a 22r, and im not knocking 4 bangers ive got one my self and thats where im comeing from im running 35 boggers and 5.29's and the lil 4 popper just dont have the power too play in mud especally deep mud like we play in, that truck i was saying is running also has a chevy 350 pushing about 425 horses so it squats the springs pretty good there with the added 250 pounds a v8 has over a 22r.
One other thing too think about is your steering even with a drop drag link when you steer it wants too make your springs flex instead of turning your tires when your lift starts too settle and flex some so hysteer is something else you might want too consider.
Sorry for the long post just wanted too give you some insight from someone whos used that lift and had the problems that come with it.
Good luck and post pics when you get it installed
