Hi I have an 04 f150 with a 6" rough country suspension lift. I have 18" dick cepek rims with a 22mm offset. Right now they only have 33's on them as that was the biggest size I could fit factory without rubbing. Would 37/12.5/18 fit on this truck without rubbing? If so, I'm going to get the pro comps this weekend. Hoping someone can help me. Thanks a million.
Depends on how aggressive they are and how much you flex the truck out. They'll fit on pavement, but will probably rub on sharp corners and in reverse. Most guys run a 3" body lift or do a level up front and AAL in addition to the lift to fit 37s
It only runs on the inside rubber of the bumper. I'll take a couple pics in a little bit. Unfortunately I got my eyes bigger than my brain. After I got these on and jumped on the highway. I realized my gear ratio is more or less screwed with these big of tires! So today I'm putting the 33's on for right this second. I only have 3.55 gears. I didn't think about my gear ratio because the 33's run without any difference. I think you said you have 35's correct? If that's right, did you change your gears? If so, what to? The 37's call for 4.88 or 5.13. I'm wondering if I would need to change gears to just jump up to the 35's. Something to lesson the gap between tires and wheel wells!! Or are 33's the biggest you can go with 3.55 gears? I'm not looking for raw power. Just don't want it sluggish like it is now with the 37's! I'll send the pics in a bit
I've got 4.10s and they work well, but I wouldn't go any bigger than 35s with them. With 37s I'd go 4.56s if the chance of running smaller than 33s is an option. If its 35s or bigger forever, then 4.88s
See that's my delima. I have a 8.8 rearend. And the shop I just talked to said they do make a 4.88 that will fit my pigs but it's a high performance setup. So that means around 350-450 for each gear. And the there's the bushing kit. That's about 350. Plus the labor. And then. Yah lol. On top of that there's the tranny bye said the tranny I have in mine isn't a tranny that will prob hold up with that setup. He said I'll probably have to end up replacing that as well. I'm just frustrated!!! To say the least. Because the 37's look so much better on it!! How much did you have in changing your gears?
I took a pic of the little rubber at the bottom it will run on sharp turns. I was going to trim that.
That fits better than I thought it would. You can swap a 9.75 axle in the back from any other F150 and lose the week 8.8 Mine came stock with 4.10s
