Height Question
The stock front end is 4” lower than the rear so raising the front 3.5” will give me a 1/2” rake, hardly noticeable. I’m going to order the readylift, readyload leveling helper air kit which should give a level ride when towing.
If it is just a super tall level -abandon that pipe dream ASAP.
Don't get all turned on over a "3.5" kit.
Leveling that much is sure to damage your front axles, without a lowering kit. The extended length upper control arms that ready lift included in some kits help with droop but otherwise do nothing to protect the axles.
If you have the same difference from ground to fender front and back, the front will look higher. Measure the gap from the top of the tire as the fenders are not the same height. You want the gap the same, so if the back about 1/2” to 3/4” higher from ground or hub center, that is very close to level. Also, measure your rear block, it should be 1-1/4” like every other F150 4wd. If you do the 3.5” RL or 3” RC kit, you can choose to not install the blocks they provide but I bet it will be nose high. All these trucks are slightly different though so +/- 1/2” should be expected.
I can’t comment on the reliability with the 3.5” kit but I ran the 3” RC kit on my 2018 4wd for 45k miles with zero issues. The cv angles are def exaggerated but my truck never saw off-road and I did use 4wd for two winters in the Northeast. I don’t recall reading about failures with those kits, so take negative comments with a grain of salt. Just because the cv angles are at upper limits doesn’t mean they are going to fail. That said, the likelihood is higher, esp if you’re off-roading. You can do the 4” cross member kit but it requires cutting the frame brackets so can’t be reversed.
