I recently did a Dobinsons IMS 1.5"/1.75" lift to my 2019 GX460, and after reading multiple times that UCA's are not required at 2" or less, I decided to stay OEM. Well, it is true that I was able to get the alignment CLOSE to spec, but it was still slightly out of caster to allow for 0 degree camber. While things were not technically that bad, the truck had a distinct dartiness on the highway. Any side winds or looking away from the road for moment, and the truck was wandering in the lane.
I got fed up with it, as I don't like things less than 100%. I picked up a set of the Ironman ProForge UCA's on the July 4 25% off sale. Install was easy as pie, quality is super high, and they are stupid simple set and forget. I haven't had an alignment post UCA, but already the darty feeling is gone and it has that nice luxurious weight to the steering again, as well as nice high speed stability.
In comparison to the SPC and Total Chaos UCA's that I used on my LC200, I like these ProForge the best. Total Chaos were squeaky and groaned, and needed constant attention. The SPC were unnecessarily adjustable, and confounded multiple alignment techs (unless you seek out "the specialist") and also needed regular attention. These Ironman look factory and require no maintenance. The ProForge bushings, while still rubber, are decidedly tighter than OEM and there is a perceptible difference in the tightness of the front suspension after install (OEM units had 17,000 miles on them).
I keep browsing threads where this issue comes up, and "general consensus" that says you don't need UCA's is not really correct IMHO. Yea, you won't smoke your tires without them, but the drivability will suffer. Just bite the bullet and buy the UCA's.
