How much caster can I get on stock UCAs with a 2 inch lift?

Got the 2" TRD factory lift and I think the dealer rushed the alignment because the camber is still off. Should I take it elsewhere for a better alignment? How much caster is attainable after adjusting for camber on a 2 inch lift?

 

Dont quote me. But im pretty sure that they should be able to get closer to 1.8-2 for caster after a 2" lift.

 

what type of lift? Struts/ springs or a spacer?

 

TRD Lift (basically 5100's)

 

Dealer should get it closer with the TRD kit. New UCA's would help though. Look into JBA..

 

It looks like everything is in spec. I’m not sure what you are concerned about.

 

from what I’ve read, JBA’s might cause rubbing since they aren’t adjustable. I want to avoid cutting.

 

It’s in spec for stock height but for a lifted truck, more caster helps with handling. Plus, I’d like the camber to be closer to zero to avoid uneven tire wear.

 

I’m skeptical of your assumptions.

 

To get 1.5+ degrees of caster with a 2” lift you will have to sacrifice some camber to the positive side. If you want 0* camber the caster will end up maxing under 1*

I think your alignment looks good.

 

not sure of your tire size/ wheel combo but this chart helped me decide and I also sent the owner an email which he answered fairly quickly.

I thought spiffy UCAs were part of the overpriced TRD lift kit..

 

Just an update. I got a quote from a local shop for $400 install and $150 for alignment for SPC's. Adding the price of the uca's brings the total to about $1400

I meant rubbing at the rear cab mount. Right now on stock uca's, im not rubbing but had to remove the mud flaps. I'm on 285/70r17.

 

ahhh, 285's. Yup - SPC's will be better for you. Make sure you go to someone who knows how to align with the SPC's if you go that route.

 

That’s gonna be a wondering dog with the caster that low. Also that alignment guy is an idiot there is no way the the specs on that alignment print out are correct. None of these trucks have 0 caster as a low end spec.

 

Just because it's in spec does not mean it's a good alignment. And unless you're in Japan, the UK, Australia or any other country where they drive on the other side, you would almost never want less caster on the right than on the left. If it were mine I'd want both more positive caster and at the very least neutral camber.

 

We can usually do 1.5+ caster on the TRD or 5100 lifts. There's even specs in the instructions. But they didnt bother to try and get it close, they got green and called it a day.

Spec for lifted TRD kit is Caster : 2.0 +/- 0.97, so its at the very bottom of the range. Ideal is 2.0.

Camber is 0.6 and toe is 0.6 (total) so its the same.

 

My dealership was able to get my TRD lift to 2.1 caster, 0.3 camber, and factory toe with little issues. Drives great in my opinion, and zero rubbing with 285/70-17 Toyo AT3’s and factory mud flaps with very minimal trimming.

 

this is reassuring. I just might have to find a better tech. Btw does your lift have any driver side lean?

 

I will just leave this here for you.

The SPC / mevotech have been good for me so far. I did have to get them close myself because the first shop i went to didn’t want to touch the UCA adjustment.
