Upper control arm questions

Hey guys,

I need after market upper control arms because I’m running a 4 inch lift and the inner tires are wearing extremely fast and unevenly. I’m looking at JBA and SPC but they are saying I might run into issue with the stock TRD pro rims and cooper 315 set up. Am I fine running them? Any suggestions anyone done the same?

 

This is what’s tripping me up

 

yeah because of the boxy design of those arms you can or will rub the uca, with a tubular uca its not an issue

 

4wp said the SPCs should work but I read otherwise elsewhere

 

@JoeCOVA @Mobtown Offroad

can either of you two maybe help out? I’ve seen you guys on the UCA threads and seem pretty knowledgeable. Yes I have a DB lift don’t make fun.

 

4wp would be the last place ide ask for what works and what doesnt, but im sure theres enough people running spcs on here to give more insight.

 

T

tell me about it 550 for labor on a control arm change lmfao.

 

This same shit confused the fuck out of me too. I have jba's but haven't installed em yet because idk if they'll work w my SEMA rims and 285's

 

It's friday so... here comes that BS from me:

I would do it right, and chop up the stock shit subframe + install the new JD-Fab subframe which fixes all the complaints seen on TW about "muhhh tires size rub" , "der caster fix after lift", "my lower alignment cams slipped ". Do it right.

cams cant slip if ya weld em to the frame

 

Not sure if I can with a DB lift

 

This dude is talking about running SPC arms not a wide ass long travel, regular alignment from total chaos would work fine

 

TC UCAs should work ?

 

I don’t know enough about drop brackets, but I would think they would. I’d call and ask them

 

yeah but you wont get the juicy adjustability of spcs. if you really need more than like 4 degrees that is

 

Hi OP,

I have JBAs and i needed wheel spacers to get the 255/85r16 adn 285/75r16s to not rub on the underside of the UCA with stock offroad wheels at +25mm offset (5" BS).

From Marlin at JBA its all about the backspace.

@Skydvrr as long as you hit the min backspace you're bueno my dude.

 

Yeah I called him he knew his shit.
He basically said I’m dumb for running 315s on the stock trd pro rims and that I need new rims or the ucas and a spacer. I’ve read the SPCs can do what I need as well. I have a headache

 

Tbh, idk what the means entirely lol. So w the semas I'm good?

 

Yes with spacers

 

Prob will rub lol. I did. CMC TIME!
