Pretty much. It's the same for the 04-08's except ours is 2.5" is max recommended. For a level you won't need to replace UCA's to be able to maintain alignment, and being 4x4 you should be able to fit a 35x12.5 on the stock rim underneath it (there's a thread on here about tire and wheel fitment on this year and I think that's what it said, been a while since I looked). I know I'm running a 2.5" level from Rancho Quicklift Struts, 1.5" wheel spacers, and 35x12.5 mud tires under my 07 F-150 FX4. I cut out a little of the plastic fender well, and a little of the bumper valence but unless you're looking for it you'd never know it was cut out.

Alex designed the Boss to be able to go to 3" because it works. I personally wouldn't go more than 2.5" but every truck reacts differently. My 2.5" level only gave me 2", Boss coilovers set to 3" might only give you 2.5". Every truck is different, just check your angles and drive around and see how it feels.


If you want to go higher than that, a full lift would be required.


I personally will be switching out my stock struts with spacers for the Boss Coilovers and plan on setting them to 2.5/2.75". It's a good look and I can install them myself with a floor jack.

Does this still remain true even with a rear block added? Or are you just meaning if i do the coils in the front to "level" and no rear block that it will throw off the angle? I must be mistaken, so the boss kit is more for leveling than a suspension lift? Cause i was looking at the 6" rough country lift but my brother told me to avoid it because its just cheap spacers and a body lift, he pointed me in the direction of the boss coil overs to go smaller and save myself trouble of gas mileage plummeting, worrying about speedometer being off and alignment issues. I am looking for a lift, a small one, that still works for off road, he said the boss wouldn't over extended and had better travel for off road than a street queen or as he called it a "bro dozer" with the 6" rough country lift.

Not sure if you already have, but check out the videos here:

I originally had them set at 2" by Alex but have since decided I wanted just a touch more height in the front. So, I now have them set at just under 2.5" in front. I also replaced the factory rear (1.5") block with a 2.5", and have 285/65/20's. In total, this gave my truck a lift of around 3" all around. I kept about a 1" rake. No tire rubbing issues and rides nearly identical to stock albeit a bit firmer (but not jarring).

So you didn't do an add a lead in the rear, just a bigger block? I think the previous owner put spacers up front cause my truck already sits level, it has what? A 2" rear black stock on the FX4?

1.75" I think, unless it was removed. Snag a pic. And its easy to tell if there are spacers up front... just look lol or post a pic of the strut assembly and we can tell you

No - no additional leaf spring was added and I only swapped out the stock 1.5" rear block with a taller 2.5" rear block from F150lifts.com. I originally thought the stock rear block was taller, but measured it and if I remember correctly, it was 1.5". Not sure if these vary based on model/trim level, but mine is a 2015 Lariat with FX4 package.

Yup you got a spacer up front 2" I think maybe 2.25" in the back you have what looks like factory blocks along with something a little extra on top of that? Not sure what that thinner plate looking thing is.

I want to say it's a leaf spring? Idk why it would be under the block like that though, no idea what the previous owner did
