These are the same product for cheaper. http://www.amazon.com/Specialty-Products-Company-25480-Control/dp/B001DBTTSO/ref=sr_1_1?ie=UTF8&qid=1394389667&sr=8-1&keywords=part+%2325480

They claim these are useful on vehicles with 3" lifts to adjust for alignement.

I used one of these for a replacement. Worked just fine.

I have them. They work great. Only thing i dont like is the ever changing bushing bullshit with SPC. They come out with a redesign every 3 weeks (dramatic). Its annoying but the UCA is a good one and i have all my adjustability.

IMHO I think a set of DSM, Camburg or a Total Chaos are a more solid option. No bushing BS, no cracking welds but they are all fixed settings. Again that is just my opinion.

Id agree for solid/jumping and heavy abuse. My friends taco with TC arms doesnt have near the alignment capabilities i do which to me is huge as i enjoy my caster maxed on alignment. His truck is very jumpy.

The max castor I can achieve right now is ~5 (probably similar to SPC). I am at 3.5 (stock range), but going back to get it set a tad higher, maybe 4-4.25 to get the wheels shifted a tad forward. Personally I don't see the need for more castor than 5... Especially at my 3.5-3.75" lifted height. I can't speak for TC or Camburg.

im just outside of 4 if i remember right. I can definitely tell when the alignment shop is lazy afterwards. His is all aligned factory spec so could be why his is so jumpy.

We're about the same height arent we?

Yep, we are both cranked a tad..

The alignment tech makes all the difference. I think I will bring mine up to 4 ish.

Forgive me if this is a noob question, but how do you change the caster with the uniball upper arms? Do you change the lower cam bolts around to shift it out and then correct the toe with the tierod?

Is this right? From my understanding, more caster will shift the tires towards the rear, less caster will shift it forward?

I've only put about 6k miles on mine and no issues. Even with a boot clamp broken and romping in Pismo where sand gets in everything. No issues yet :shrug:

The upgraded UCA's are castor corrected which allows the tech to change the castor to the proper amount via the lower cam bolt.

I am not a tech, so I am not 100% how/what gets adjusted other than the cam bolt. I bet someone else can chime in with more info.

Brutal, did you have this installed backwards? IIRC, on the gold bracket/spacer/sliding do-hickey, the SPC logo should face outwards (the rounded side) versus the opposite (flat side). Perhaps I'm looking at this wrong or you had a older model.

Crossing my fingers I got a good set. I know a handful of people on the forums have had issues with them before. GL with yours OP.

EDIT: NVM, looks like you're right. My memory is shit. See 3:30 in the install video. OP just FYI there is a video installation.

this is correct.....most aftermarket arms have i think almost +2* caster built into arm.....
check out the manufacturers specs on arms before purchasing
and like above ^^^ then its just the factory cams to be adjusted.....
assuming yours have not seized due to Toyota's in ability to use grease on then...errr
don't get me started on that one either
g/l to all

they are adjustable so technically thee is no right side to face out
that is the neutral setting which is +2* if i remember correctly...
that being said
i have had my POS arms in and out many many many times....
i fully aware of how they install unfortunately
spc was good about it there customer service was great at first.
but it still gets old swapping in and out the arms and bj's
then almost 1 year later to date bj's shot again...
call sorry that's a wear item ...really 30k is all you get out of them
i have pics of a new one they sent where u can see pitting starting already on the joint....
some are greased some are not much if any.....
crap if you ask me....where is quality control....
i think i was at 3 different bushing stlyz all because of failure
i just cut out the old bushings and installed their "NEW" ones for $25 and i see now it looks like it has changed again.....
f that for an extra $200 get some tc, dsm, camb.,ect.....
i just picked up a set of ready lift ones.....i will report back on them

this is my opinion from MY PERSONAL EXP.


i also know a guy whos cracked at the weld and he never wheeled...
i will try to find that pic

Rancho or Mevotech Adjusrable upper control arms

Has anyone tried the Rancho or Mevotech Adjustable upper control arms? I'm trying to restore factory castor settings to stop the front end from darting.

[RedRumt4r]

man those UCAs looking no different from the stock control arms except it might have upgraded bushings and this adjustable ball joint..

http://www.spcalignment.com/index.php?option=com_spc&task=part_description&pid=67125

can someone confirm if these balljoints in the link are the exact same ones SPC sells in that full UCA swap kit?

None of those UCA's listed there are adjustable. They're all OEM replacement parts. Only adjustable OEM parts listed are the LCA's that are done by the cam bolts.

 

[inscarguy]

i have had them for 3-4 years now. not 1 issue. same bushings, same ball joints, no wear on tires.

get alignment every year, grease ball joints every oil change.

took it to get an alignment this year, did not need it. settings did not change.
