Can you increase caster on stock UCAs without rubbing?

I’m just barely not rubbing on 33’s and a 2 inch lift. I currently have about 1 degree of caster. Is it possible to increase this without pushing the wheel further back? How much should I be able to achieve on stock uca’s?

 

If youre only at 1 degree even then a good alignment place can likely get a little more positive caster to help. 1.0 is very low overall. Probably getting some wandering at higher speeds right now.

I would start w a good alignment place and skip the cheapo places.

 

If they increase caster by pushing the lower arms forward, does push the tire forward or backwards?
