Thread: 4L80 swap

  1. #1

    4L80 swap

    Into an SSS, do I have to put a 2" body lift to make the trans clear the tunnel? I am thinking of grabbing one for a swap in the future, but I don't really want to put a 2" lift on the truck to make that happen.

    You won't need a 2"--you need a 6".

    It'll fit just fine! (with some other drivetrain mods)
