Will 37s fit under 4" lift on 99 Superduty?

[99Superduty78]

I have a 99 superduty with a little over 4 in of lift in the front. It started as a 2.5" leveling kit and I added mini pack blocks underneath and is closer to 4.5" and have not had any problems. If anyone has pictures or knows of 99-03 superduty with 37" tires on oem wheels, I would appreciate it. I'm going to run 07 or 08 oem 20s and I haven't figured out the backspacing I need but that will come later thanks.

No, they won't fit without some serious rubbing unless you trim your fenders.

I'd also recommend getting rid of your front blocks.

I have heard of very few people doing so but have heard of 37s clearing on 4" with no trimming. I have a Ranch Hand front bumper so i'm not worried about front clearance. Why would you recommend removing the blocks? I know it's kind of a ****ty way of doing it, I should have just gone with a 4" but I wasn't planning on going that high.

Also, have you seen a 99-04 with 4" and 37s or just heard of clearance issues? Thank you in advance

run a 9" wide wheel / with -6 offset. this setup with a 37 only haas minor issues with the fender liner. it can be easily massaged with a heat gun. looks great as well

Thanks, I was just looking at your truck on an older thread, it looks great, I also have the same color green as you. Did you just heat up the plastic and push it back some? I would rather not do any trimming and I'm pretty set on the oem 20s with a 2" spacer. I have seen few with this setup some with trimming and some without. Thanks again!

A 1.5" square tube spacer between the frame and the bumper works wonders for tire clearance.
