Default which control arms do you use/recommend?

so thinking the next step in beefing up the front end should be the control arms

Cognito

or
http://cognitomotorsports.com/store/page141.html

for the lower control arm, im not seeing alot out there for aftermarket, just the standard OEM replacement stuff.

so your thoughts?

Default Re: which control arms do you use/recommend?

If I remember correctly from my discussions with Cognito (when I was trying to make the exact same decision) the Uniball Upper Control Arms (UCAK100044) are not recommended for environments where there could be exposure to a lot of salt. They explained that the uniball is not protected by any type of grommet so the parts would wear faster if exposed to salty air (near the shore) or salt/calcium used to salt the roads in heavy snow areas.

I went with the Upper Control Arm Kit (UCAK100001)...they said this provided a more protected setup that would not be as open to damage from the environment. I also included their Pitman Idler Support Kit, tie-rods, Idler Pivot Assembly with Weld in Gusset, and Billstein shocks. Been running that setup for a year or more now...no problems. My truck is leveled using this kit and actually rides much better then when I simply had the torsion bars cranked with the Truxx keys.

looking at both items, it does make sense what you are talking about. the 044 is clearly more exposed than the 001 is. I live in minnesota, so we use crap loads of chemicals on the roads in the winter...but... what are the trade offs here?

maybe someone can chime in who is/has run both models?
which one is better?
is there any benefits/cons to either model?


the less stress i can take off the front end parts, the better. while the 001 seems logical, i guess im looking for more info. i would hate to drop $500 on the parts, just to find out the extra $$$ on the other model would have saved me alot time in the future if i wanted to upgrade/add or replace something that wears out.

The uniball joints in the 044 arms are not replaceable, whereas the ball joints in the 001 are. Four bolts holding it to the underside of the UCA flange (assuming you are leveled, else instructions state to mount ball joint to top side of flange). I just installed the following last week on my 2008 SUV:

o UCAK100001 (Cognito - front end level kit)
o BILSTEIN-BE5-E381-T0 (Cognito - longer-than-stock shocks for use with UCAK100001)
o SBELKHD-1000 (Cognito - end-links for use with UCAK100001)
o PISK2008 (Cognito - pitman/idler support kit)
o Kryptonite tie rods from dmaxstore
o RS5407 (Rancho steering stabilzer)
o GM green keys (15592573)

Very happy thus far!

Regarding my set-up, which is almost the same as KT2T's...I don't remember exactly how many inches that gave me, but it was enough to level the front with the back.

I had the dealer do all the work and they took their measurements using the rocker bar as a guide. They tweaked the torsion bars until the measurement at the the front of the rocker bar (just behind the front wheel) was the same as the rear of the rocker (just in front of the rear wheel).

did you get the stock height one for the sway bar end links?
or did you go to the 4 to 6 inch lift one?

also, did you leave the T bars stock, cranked, or lowered?

i had my T bars cranked up, not maxed out, but somewhat close. i lowered them when i put in the new UCA, and regretting it since. now i have to correct them all over again to level it out better. will prolly return it back to where i had it.

i did get the Bilstein Front Shocks ( dont remember the model # tho) and im not too impressed. i liked the firmness the stock shocks gave me ( i know it was because they were maxed out tho) these ones seem too mushy, and bouncy.. so they might end up in the classifieds before too long.

only had them on for about 1.5 weeks... worst case, i move up to the dual shock hoop... ouch.. my wallet..
