    Stick with the Dorman ones, then. They'll be better than stock but still look like a factory piece. Or you can pick up some GXP ones, like Guz said, and they'll still look stock but perform quite a bit better.

    I wanted to help stiffen the rear suspention on my '04 Monte Carlo. I pulled the stock trailing arms and put on a set of arms from UMI Performance. Can't say I noticed much as far as a difference (a little firmer/stiffer take off, but next to no one would ever notice that).

    I have my old stock arms in a box. They have about 55K on them. I bought the '04 Monte in Septmber of '08 and it has not seen snow since I bought it.

    I'm more then happy to sell the stock ones. If you are interested, PM me if interested (if your serious, throw me a price and I can get a shipping quote). I would be happy to see them leave my garage and someone get some use out of them.

    If you're going to go aftermarket, I am thrilled with the craftsmanship of all the UMI stuff I bought for my '84 Camaro (hence why I chose UMI for the W-Bod arms).

    If your stock ones you're trying to sell aren't tubular i'm going to have to recommend the OP skip them just based on how much of a PITA these can be to replace.

    As for noticing the difference... it just tightens up the rear end... of course you're not going to notice a difference in a launch. Try a corner for a change.

    There non-tubular, hence why they are stock. I replaced them just because I wanted to stiffen the rear end (outside of that, they are in great condition).

    As for being a PITA to change, not sure why. Admittedly my only pain point was not having an impact gun available (breaking the bolts free holding the arm took a lot of UMPH). Out side of that, changing them was a breeze, easy, straight forward.

    As I stated, if I were going to buy a set new, I too agree with going for a tubular pair (hence why I recommended ordering a set from UMI Performance, like what I put on my Monte). The tubular ones will function better then stock. Just my opinion.

    I replaced my stock trailing arms with a set of GMPP trailing arms for $36 for the pair (they are tubular versus the stock ones that are u shaped) but I don't believe they are available any longer. For a street driven car (not raced), they would be perfect if you can still get them. Mine were very easy to replace-no issues, very straight forward-car had 90,000 miles at the time. As noted, an impact gun makes it very easy! The front lower control arms were real easy as well, just to note.
