Rough country upper control arms?

[coppertahoe]

Hey everyone, i have my tahoe currently cranked and blocked. I dont have any really bad angles in my front suspension, but was wondering if i could benefit from the rough country 2-3 in upper c arms? I know I could crank it even more with those, but they obviously wouldnt help with the lower c arm ball joint angle so i would leave it how it is presently. Just want to see some of your guys' opinions on how i could possibly benefit from these, i was just going to buy stock upper c arms, but the rough countrys look to be built well with moog parts

Heres a link for them http://www.amazon.com/Rough-Country...ugh+country+upper+control+arms+98+chevy+tahoe

if you use those for 2-3 of lifts with without dropping the differ you can start kissing your half shafts goodbye.

^^^^ this. Get a real lift that drops the differential down

i've installed the Rough country 2-3" lift on my 97 2 door with those control arms.. They seem to be well built, wish i can say the same for the rest of the kit.

I do however have a very slight vibration from the driveline when i accelerate from a stand still (not WOT, just regular acceleration). Not too sure what this is from or if its related to anything from the kit.
