Thread: so i have questions about sway bars.

didnt see it anywhere here...so. are they worth replacing? i mean they have kits with sway bars and bushings claiming theyre bigger and stronger but ive done measurements and my bars are the same size as the aftermarket. so whats the difference? are they better material or bent differently or is it just the bushings that make a difference? any help? this isnt my field but id like to have this knowledge... thanks guys.

do the aftremarket ones break as easy as the stock ones (sway bars) or are they made out of the same material?

heck yeah it is I don't know how many I had to reweld or epoxy, or replace but it's like that on ventures, centurys, sillhouettes all sorts of gm cars.

what kind of trailing arms are you talking about, bio? the ones from zzp? or somewhere else? i have to do some suspension work (i.e. struts, lowering springs, strut mounts, maybe sway bars, and now trailing arms lol). thanks.

ahh, i didn't know GMPP made anything like that, are they still avail. from gm?

^^^thanks. i'll look into it, since i'll be diving into some suspension work soon.

i hate to intrude on the topic. but do grand prix's of the same body style have the same sway bars? for instance does a 98 grand prix 3.1 SE have the same sway bar as any other simaler body style grand prix?

Yes, I believe, that all the 01-03 GP's have the same sway bars, front and rear, the springs rates are diifferent. Definitely, the 2001-2003's. I think that the 97-00's may have different size bars based on gmpartsdirect.com since they listed the early years differently, although the price is exactly the same, thus my being unsure about the earlier years!

thanks, i'm sure it'll be easier to find the UMI arms, than a set of orig GXP's? Hopefully when i go to do my work, i'll be able to find what i'm looking for. Where can i buy a set of UMI's if i cant find a GMPP part?

is the quality the same between all these brands? or is it just a price/name brand difference?
