UCA Upgrade

Setting E then 75% of caster on the lowers will treat you right

 

What size tires and wheels are you running for those settings on your SPCs?

 

285 but this is the setting to push your tire as far forward as possible. so good for 34s, 35s etc. You may also be able to run setting F if needed.

its less about caster and more about shifting the UBJ and wheel forward.

 

I just got my SPCs installed a few moments ago. No more CM rubbing! The Icon UCAs rubbed.

 

I have the eibach 2.0 coilovers. I only lowered the right side very so slightly to make it level with the driver side. I have rock sliders, and winch, and sso bumper. I have a set of 285 75 16 on -25 FN wheels that I want to put on my truck. My current wheels are stock with 265 75 16 toyo at3. They are not wearing evenly and becoming very noisy quickly. I'm sure it's a alignment issue. The bigger tires and more negative off set rub which I did expect to happen. I only test fit them and didn't even leave the shop. So now my goal is to get a proper alignment and make the tires not rub. I'm pretty sure I'll need a cab mount chop no matter what I do but would upgrading the uca help with the alignment and maybe help the rubbing some? I'm looking at going with camburg or dirt king. I want to be able to have the simple moog ball joint replacement option. I'm just not certain that spending the money is going to help me.

 

I would never get spc arms again. I have jd fabs .75 ucas now and couldn't be happier
