New UCA's with these alignment numbers?

I'm running a 2" lift on 5100's with OME 887's. Shop said they couldn't adjust the caster any more for the passenger side. Truck pulls to the right noticeably. I just swapped out the stock Wranglers for Duratrac's and the problem is still there so I know it's not the tires.

Does a 2" lift with this barely in-the-red caster justify new UCA's?

 

UCAs no question about it. if you care about on-road handling, particularly highway stuff, then target over 3deg caster, and go as close to zero at your camber, keeping it even L & R, and try to stay with factory toe-in or close to it: 0.05deg toe-in per side also even L & R.

 

You need UCA’s.

 

I accept it's not a race car and I intend to wheel-it so on-road performance isn't the biggest deal. I just don't want it to pull to one side and wear the new tires out. What UCA do you recommend? SPC? JBA?

 

for you i don't think it matters which ones as long as you can get more caster and push into the 3+ deg range. both will do that. SPCs can typically go further with caster. i have SPCs myself.

 

The price of SPCs hurts my soul but I'll look into them. Thanks for all the help brother

 

I have JBA's and they are pretty good, they will fix your alignment issues. SPC's will give you much more adjustability if you're going to go bigger than 33's

 

I'm probably not going bigger than 33's but I've said I'm probably not going to do a lot of things and I keep doing em so. Do you have the HD JBA's? I assume they're not needed unless you're wheeling hard

 

I’m in the same position you’re in and I think need UCAs too

 

I have jba’s and 4* caster no problem.

 

Just standard duty High caster. They are pretty beefy already lol, i highly doubt you'd have issues with them.

 

Yeah i'm at 4.5 degrees and the truck is riding great. The problem i've been seeing is alignment techs dont like to touch it because the number is so out of 'spec' which can be annoying lol

 

What's your thoughts on a lower drivers side caster to compensate for road crown (+/-0.5*)?

 

that is some stupid bullshit. full on stupid. i don't need that kind of help driving.

but you didn't ask me. lol

 

I'm not really an expert on the subject matter but from what I know its personal preference. Some people/shops like to add it, and some don't. I don't think it makes a huge difference regardless.

 

haha especially if you drive on a road without road crown

 

Haha good to know. I'm just reading other posts on here and it came up. Never thought about it until now

 

Very true. Many techs are not used to someone asking to purposely put the caster out of spec 1.5-2 degrees.

 

it's just some old school thing from back in the day when 2 lane roads were what cars were about and road crowns were significant and everywhere.

when's the last time you actually noticed one, enough to compensate for it? uneven caster changes the steering wheel's weighted feel across the sweep of the steering. 0.5deg isn't huge, but it's enough to change the feel left to right. not a consideration for many. speaking for myself i'm a kart & open wheel handling whore, and i've setup my truck around this level of response & handling. with everything i've put into it, i'll be damned if i'm gonna choose to make it wonky with an asymmetrical alignment. those only make sense on race circuits.

 

how much caster can you get out of stock upper and lower control arms, on the 3rd gen? Ski
