Understood. I would stick with rough country for Fords only because I owned a few and used these kits and really liked them. I am sure there are others that are the same or maybe even better. However, when I compared prices they were about in the middle.
Just something to think about since you already have the spacer which would be part of a leveling kit, you could just get longer control arms and probably fix the noise.
However, if you need new shocks also, look at this actual lift kit I attached. You would get control arms, shocks, springs, and blocks for the rear to match. So it maybe cheaper to find a kit like this and replace the whole thing like you are thinking.
Since you mentioned towing and using the truck, you may want to call Rough Country or whatever company you decide on and ask if they have a staggered kit. Like a 3 inch up front and 3.5 in the rear because if you are loaded most of the time, that will keep your headlights from pointing up in the air when you are towing or hauling anything. Plus it won't look much different. I bet they would just send you another 1/2 inch block for the rear if they don't have a 3.5.
Just a thought. You can't go wrong either way. I attached a picture of this kit installed on your truck. Looks great!
