The stock stamped u-channel trailing arms on my GP are bent. Looking to replace with tubular ones. It's not a racecar, so I'd rather avoid going BMR or ZZP or whatever if something cheaper will do the job. I've seen people say that GXP trailing arms are tubular and will fit... and are relatively cheap. It's '04+, but doubt that would matter.
If it's the way to go instead of spending $120, does anyone have a part number?
Oh... just found it, I think. Don Rom posted the p/n on gpona. This look right to you's? 15856683 - GM ARM
