I make these custom rock tamers for any style vehicle. I use inch and a half square tubing and 1/2 inch thick rubber. I also coat all the steel with Hurculiner. As you can see in the picture I also have two 1/2 inch locking bolts that tighten down on the receiver so it will not move.
I make these for 2 inch and 2 1/2 inch receivers. Any questions give me a call. Thanks Mike
