Thread: Viper rear bumper on SX

  1. #1


    Default Viper rear bumper on SX

    So, bought a Viper rear bumper and cover for my 700sx.
    Thought it would bolt right up, but not the case.
    Anyone have pictures or info on how this is done?
    I have an idea, but I donít want to start doing things that canít be undone.

    If I remember right you also need the viper back aluminum piece that rivets to tunnel. I did this to my 98 xt.

    I wonder what you do with the stock heat exchanger.
    Looks to be enough room to go above it, and below the top of the tunnel with the new bumper, but I wonder if it will fit to the new back aluminum piece?

    It should fit just fine. I had a viper heat exchanger on mine. Pretty much change whole back end to a viper.
