Can you add aftermarket UCA on a stock Tacoma?

    yes 3rd gen dcsb.

    just keep in mind what many of these guys here are referring to, that if you do a dialed in setup without a lift, after you install the lift it will be starting all over and you carry nothing forward except your actual uca's. but hey, i did that, no prob. this truck is constantly evolving.

    Absolutely. Still can use it to help adjust LCA cams so you can push the wheel forward and away from cab mount, firewall, etc.

    I’ll be doing it myself.

    Are you sure you can’t increase caster to your liking without installing an expensive aftermarket UC?

    FYI, I have SPC UCAs that I installed as part of my overall suspension upgrade.

    not enough to satisfy. oe ucas do not go into higher caster enough to open up the driving.

    To each his own! I wouldn’t go through the cost and effort of installing an aftermarket UCA to increase my caster beyond the normal range because I thought it improved handling on the hiway. I installed them to fit my king coil overs, keep my alignment within spec after a 2” lift, help my 33” tires to fit, and increase my travel by 1”. :)

    If you're doing it yourself you don't have to worry about it. If you're having a shop do your lift its cheaper to install UCA's and the lift at the same time as there is some cross work that goes there.

    yep. there are two approaches to alignment that you see here on TW. the main one is fitment, like you, and yeah i need all that for my new hardware as well. but the other reason is rare around here, handling, driving dynamics, etc. not as many of us driving/handling folks around here.

    I’m not sure I follow. My overall goal was to upgrade the off road performance of my truck (which includes handling, driving dynamics, etc) while minimizing the downgrade of it’s on road performance. It has never occurred to me that increasing my caster might help my goal.

    I'm not arguing with you or anything.

    you can go into all kinds of details beyond a correctly performing lift. but that may not be worth it for many. high caster won't matter at low to mid speed. but if you go higher speed more caster can help your handling performance if you can drive it well. e.g. a mid to long travel suspension requires lifting the throttle going into suspension events to keep the chassis balanced when the suspension cycles. more caster hugely improves this. there's quite a bit more.

    i paid dearly for my suspension like you. but then i went to town to isolate the suspension's attachment points to eliminate flex there, giving it all to the shocks & tires. like you said different strokes. achieving high caster after all the work was a main strategy for my truck.
