Time is getting close and I am going back and forth.
Toytec B.O.S.S w Bilstien 5125s
Toytec Ultimate w Bilstien 5125s
Icon set up
UCA's with what ever lift I go with.
I hate making decisions....haha
My wife's 4Runner has never seen any hardcore off roading and likely never will. Upgrading to the Icon suspension was one of the best decisions I've ever made! Icon provides a significant step up from the Toytec stuff IME and on road/mild trail usage the difference is noticeable/appreciated on a daily basis. I'm not saying Toytec CO's suck, I'm saying ICON is worth the up charge and then some.
If it were me and I was looking for UCA's for a mostly street driven vehicle where I didn't want to lose the reliability/quiet/low maintenance of my stock UCA's, there's only one choice - Camburg.
Camburg Upper Control Arms Set - 310040 "Ball-Joint"
Press out your factory ball joint from your factory UCA and press into the Camburg UCA. Now you can get 4+ caster on alignment even w/ 2.5"+ lift. You have the reliability/reduced maintenance/quiet (no squeaking) of a Toyota ball joint. You will have improved range of motion, though not as good as a uniball, nor the strength of a uniball if you are really bashing it hard off road.
Moog ball joints are available as a replacement or pressed in as ordered w/ the Camburg UCA's. Moog ball joints aren't as good as the Toyota ball joints, but they are good and about 1/3 of the price. On a low mileage vehicle I would use the factory ball joints and drive them for 100K+ miles until they fail, then replace w/ Moog. Camburg UCA's w/ ball joints are NOT as good for a hard core trail rig as a true uni-ball set up. For a daily driver, they give you 80% of the benefit w/ none of the maintenance/squeaking you get w/ the uniball set ups.
Light Racing offers similar ball joint UCA's for less $, but you could fill a book w/ all the the Light Racing UCA failures I've seen here/Tacoma World. They have always stepped up and taken care of their customers, warrantied their products - frankly I'm not as interested in a warranty as I am in not needing the warranty to begin with. LR UCA's are just not a product I'm interested in running on my 4wd.
