DaMonkey You're right. I'm evaluating all options.
There wasn't much talk on here about JBA compared to others. Hopefully this will be a good reference going forward.
Thank you all for your input.
I emailed JBA regarding fitment since they only offer the high caster arms for 3rd gen 4runners. I got an instant response saying they're appropriate for 1-4 inches of lift, pretty much the same as Camburg. I should be fine with my taller 99 coils right?
toyotaoffroadaz did you end up getting these UCAs?

My UCA bushings and ball joints are worn out so I'm shopping replacements. My mechanic is recommending Camburg at $699. JBA at $460 is attractive, plus the 5th gen guys...
