How necessary are UCAs on a 2-2.5 inch lift

So, in a couple of weeks me and my brother are going to be installing Bilstein 5100 shocks on all 4 corners, OME 2887 springs, a 1/4inch driver side spacer for the taco lean people tend to get with aftermarket suspension and an HS Deaver AAL. I got all the suspension components from HeadStrong Off-Road(really quick delivery and good customer service by the way). I’ll be putting the 887s on the 4th notch on the 5100s and am anticipating a 2 inch lift according to Headstrong's chart on their website. I saw on a couple of threads that 2-2.5 inches is maxing out the stock UCAs. Is not putting on an aftermarket UCA going to mess up the stock UCA and the tires in the long run? Or is it mainly for something like ride quality or a mix of both. My Tacoma is pretty new I got it this past November. I decided not to buy UCAs because from what I understand most quality UCAs are around 600+dollars which would essentially almost double the price of the rest of the suspension which I got for $798. If I do have to get UCAs any suggestions on quality budget ones?

 

You shouldn't need to preload the struts, you're adding lifted coils.

UCA's allow for more articulation, better ride comfort if they're built right, and mainly a better alignment when it's lifted. They aren't necessary with a 2" lift, but 2.5" or more you start to run out of caster, so it doesn't drive as well as it should.

 

I have 2” on mine and didn’t need them. Made it easier to go to 33” tire as we were able to move it away from the cab mount with caster adjustment on lower control arm. That solved both the caster and the tire clearance problem. YMMV

 

Might wander around more around 45mph and faster.

 

I’m running the 887 and OME shocks and while not necessary like others said the UCA helped clear and align my 285s

I have a similar lift and only upgraded UCAs bc of a tire rub with 285s. The drive was fine before but i will say it does drive better now with JBA higher caster.

 

How long have you had the lift for? And did you experience any sagging?

 

5100 fronts are already extended length. I just add an extra circlip on drivers side and nix the spacer.

 

about 8000 miles , a year. No sagging I see but I’m going to measure tomorrow to check
