2002 Yukon Vs. 2wd Suspension Question

[pandoraskeeper]

THE NEWER YUKONS SHARE THE SAME SUSPENSION SET UP IN THE FRONT AS THE 4WD FULLSIZE TRUCKS, FACT. IS IT POSSIBLE TO SWAP THE UPPER AND LOWER ARMS, SPINDLES AND ALL FROM A 2WD TRUCK INTO PLACE ON THE YUKON SO THE THING CAN BE LOWERED PROPERLY WITHOUT USING THE STUPID TORSION KEYS?
I AM AWARE OF THE DIFFERENCES BETWEEN THE TORSION BARS AND THE 2WD SPRING SETUP, BUT THIS IS ALL IN THE NAME OF A SOON TO BE HAD AIR RIDE TECH SHOCKWAVE SETUP..

I'm pretty sure you could swap the upper and lowers with no real problems. I've seen bagged escalades with DJM tubular uppers. They make a torsion bar lower control arm also but if u scrap the torsions, not really needed.

The mounting locations I think are universal on all the trucks. Only thing is you have to check to see if the spindles will accept the cailpers....the Yukons run larger brakes then the pick up trucks I believe.

I also think you may have a upper coil perch as well, if not you'll need to fab up upper mounts for the shockwaves.

You may be able to get away with a tubular upper and shockwaves, just depends on how low u wanna get.

No, the control arms are a totally different size than of a 2wd fullsize pickup. I have looked into this and it will not work. You can order up DJM drop control arms to do the same however specifically for the Yukon.

As far as the control arms being different......in what ways are they different for future reference.

[Mark]

the distance between the lower control arm mounts ( bushings) is greater on the SUV's.

I needed to know too lol and couldn't get an answer anywhere.

thank you all for the info, everything makes sense. i had a good feeling that there was more than just brake size difference between the two setups. and coincidentaly we are planning to do just that, the shockwave air ride tech setup, and also going with 22 front and 24 rear instead of the current 4x22 setup. also running hopefully much lower profile on the front, and getting it to come a couple inches from laying frame while moderately tucking f&r at total bottom, but not to lay.. now to my point........i feel retarded even asking this since i do all my own suspension work, always have, and the majority of my mechanic experience in the field was as a suspension and alignment tech. maybe the answer to this question is something that is just "understood", and i'm the idiot who's just not getting it. or i can be saved by one of you. lower control arms, torsion keys, bla bla bla. i know what there suposed to do, now upper control arms are a different story. the aftermarket ones i mean....when shoping for lower control arms for this truck you will find djm, belltech etc. for the lowering equipment. these companies also market custom UPPER arms, but i have yet to se a photo or graph comparison to show how and where they benefit over stock. do they merely have a better apearance or sportier look? i don't think that would make a sh!t to 90 percent of people. if you wanted the looks that badly you would have them custom made and chromed, problem solved, no one else biting your style. nonetheless, never is it said that they help to right sh!ty balljoint angles, or wether they compensate for excess negative camber whith the lowered suspension? sorry for being long winded.
with the simple keys and springs belltech kit, the baljoints are at unfavorable angles, and the camber is off noticably and actualy by about 3 deg. negative. I THINK THIS LOOKS LIKE SH!T. the cams are maxed, and toe is set, but caster and camber are s.o.l. phew...knuckles crack.... all i want to know, all that being layed upon you, is in the case of say DJM upper control arms. do they increase the amount of positive camber you can get so your wheels will stand with a little posture at a not slammed, but prety damn low stance? and do they correct for crappy balljoint angles so yo shat don' get wo' out? if you actualy read this far, you are very patient. i am serious, i've tried asking everyone i could find that may know, to no avail. they all look at me like i'm an idiot. so any help would rule :rocking:
if you're still reading you are still very patient, i feel you will be rewarded with great things. lol;)

you pretty much got it "understood". The upper control arms are for basically aiding with alignment (caster/camber) when used with a drop kit.
