I bought the supersliders from Rocky road outfitters. The build and finish is top quality. The directions are for shit though. If you have a trd pro follow the trail trim instructions. You will not need the spacers they give you for the fuel line. They went on quick and easy enough. They tell you the bottom hole in the middle bracket is no longer threaded on 15-16 year models. They also say it is not needed. They seem solid as hell. I'm not worried about it.
