2008 limited uca ?

[swegen]

front springs from a 4WD FJ, 5100 bilstiens zero lift position, 265/65/17's, 1.8° caster each side. Would like to get 3 or more °.
I am unhappy with the twitchy directional control and I am looking to replace UCA with something that will get me better straight line stability.
Been looking at a lot of UCAs but can't get a straight answer on what the resultant caster will be.
Anyone have info to solve this mystery?

Just buy SPC. It's the UCA with the highest degree of adjustability.

IF you're willing to learn how to adjust them, then SPCs are the way to go. Or if you have a local offroad or alignment shop that knows how to adjust them. I do my own alignment with a tape measure and an angle finder now with my SPCs

if you dont want to adjust them or don't have a place to align them, then fixed position arms like Apache Offroad or dirt king are good options
