I just purchased a 2005 f150 supercrew I purchased a 3.5 inch coil spacer for the front and 2 inch block for the rear. It's 2wd what is the biggest tire that will fit?

i don't think you want to go with a 3.5 spacer. check out the other threads before you do anything.

Yah 3.5 is crazy talk. You'll deff run into some problems with the UCA and some rubbage on the coil spring. 2.5 is the most I would ever go and 3.5 is an 1" taller. Think about it

I wouldn't go bigger that a 2.5 spacer on these trucks. Check out the sticky at the top of this forum about wheel fitment. You should clear 295's though with that set up.

If you go over 2.5 inch spacer the steeper angles puts more stress on the ball joints and other stuff causing them to wear faster

I don't see how you could fit the coil assembly in with a spacer that size. I had a little bit of a time getting mine in with a 1.5" haha

If you read on ebay, the places selling the "3.5inch" level kits state

"The front lift spacer is NOT a 1:1 ratio in terms of lift amount to thickness of the spacer - Meaning that the lift height achieved is much greater than the actual thickness of the spacer. The reason being is that the lower control arm compounds the amount of lift due to its angle and length."

Therefore the spacer isnt 3.5" tall. Ive researched and some sites say the 3.5" space measures 2.5".

Hope this clears things up.....

With the level kit on a 2wd i would run 33-34" tires.

that is true they are not 1:1, but that is still a rediculous setup. im not hating im helping. Maybe 2wd are different than my 4wd but that wont even work on mine.
spacer thickness:........ Amount of lift:
1 1/4" ............................1.5"
1.5" ................................2"
1 5/8" ............................2.5"
1 3/4" .............................3"

I did a write up on my setup: https://www.f150forum.com/f4/6-rough...-77531/index4/ page 4, post number 38.

Yah of course they are not 1:1. But some ppl on here are having problems with he 3" pulling the UCA down and hitting the coil assembly. That being said another .5" would prolly cause more problems. But our truck your opinion. Try it out and let us know how it works out! Might be fine. Could run 35's prolly no problem. Depending on wheel specs
