0 Offset, Fitting 35's (almost)

Hey guys, Ive done a bunch of reading and just am left confused. I also don't know the science with alignments so I figured id post my question here, & hopefully find an answer.

I have a 2.5" fox lift, SPC control arms, have had my CMC done, and trimmed the front bumper/liner. I am running 35x12.5x17's ridge grapplers right now with 0 Offset...

I am not rubbing anywhere unless I'm at full turn, I rub on the UCA.
so for example. if i'm at full lock turning right, the Left wheel inside part of the tire will rub the front/ underpart of the UCA.

I had an alignment done and thought that they would push the caster all the way on my UCA's, in my head i feel like it would clear the control arm just barely enough? or am i completely wrong with that science? lol

I know like a -12 offset is good to clear the UCA and not have to worry about hitting my cab mount again. and i think the smallest reliable wheel-spacer is 1.25".. i think that will for sure make me hit the front bumper or cab mount right? has anyone fit 35's with 0 offset? or am I out of luck and just have to deal with the rub at full lock until i can get some new wheels? or will the caster pushed forward do anything?

thanks guys!

 

If you haven't already, I suggest reading through this thread.

I've never heard of anyone solving a UCA rub with an alignment. I think that is typically solved with offset/backspacing.

 

Do you have the print out from alignment? There’s isn’t that much difference between 2nd and 3rd gens and I’ve been running 35’s on 0 offset wheels for a year plus and have zero rub.

oh never mind I just noticed Spc uca. I think the design of them vs others like TC or camburg probably is the difference.

 

Yes let me upload a picture.
Here:

 

If you're rubbing on the UCA then you're going to have to get a spacer or different wheels, an alignment won't fix that. I'm curious to know where on the UCA you are rubbing though. The width is generally what matters on that and most 33s are the same width as those 35s.

 

My 33's before this had no rub. i think its just the wheel being taller? I would run a spacer if i knew if it would work and i wont hit the cab mount or bumper because 1.25" is a lot compared to a -12 offset.

heres a pic of where i'm rubbing.

 

well you went from probably a 285 to a 315 which is over an inch wider. maybe two.

 

Adding a 1.25" spacer will push you in to your cab mount a bit most likely. You can run a smaller spacer though, I personally wouldn't go 1.25" but stick with .75"-1" and shave the studs if needed. (Well, if it were me I would buy new wheels, not a fan of spacers). However, since you've done a CMC you may be ok. With the SPC uppers, you can adjust your LCA bolt closest to the cab all the way out and the one closest to the bumper all the way in and then do the alignment adjustment with your SPCs. This will pull your wheel away from the cab. Since you've cut your front bumper, you probably won't have to do anything more up there but it's only plastic if you do

 

Actually it can, especially with the caster number he has and where it is rubbing.

With 35’s you’ll want to be closer to 5 degrees. That looks likevery light rub. The addition of caster may help with that and will probably feel better while driving as well.

 

So maybe ill take it back to the alignment place ( since im drifitng to the left anyweay) and have them just adjust the caster forward all the way and see if it helps. if not oh well. ill just leave it how it is and get new wheels eventually. if anyone has a link to hubcentric .75 spacers ill check it out.

 

don’t ask them to go all the way they will duck it up. Ask for 5 degrees and go from there.

 

There’s a goldilocks balance. Just enough offset to avoid the UCA but not too much to hit inner fender and cab mount.

Alignment won’t help. Need a spacer or bigger wheel offset. Quarter inch might be enough. Just make sure you have bough threads on your studs.

 

You don't think adjusting the ball joint setting will help? in my head it makes sense when looking at the wheel/UCA that adjusting the "plate" and adding the caster that way seems like it would push the wheel forward from where it's rubbing. but yes a spacer would def do the trick. im just nervous about the thinner spacers & reliability

 

This thread will help answer some of your questions.

What’s the backspacing on your wheels?

 

...which then will cause the tire to rub spot welds and cab mount...

 

its a 8.5 wide rim. 0 offset. so i think it's 4.75"

 

Hm? The OP states 12.5" wide tires which are 317mm (basically 315/70R17). A popular width for 33" is 285mm which is 11.2".

 

Here is another picture of the rub. still wondering if caster would push the wheel forward more to not touch the UCA?. I love the look of 35's and it does great offroad, but man is it a pain sometimes lol
