The bumpers are built to be beat on, abused, bashed on rocks and come away doing their job every time. The 80 series is a very capable vehicle and we set out to provide products to compliment and strengthen what it already has built into it. Our business focus has been on building quality product for fullsize trucks and SUV's. We don't build products for Jeeps. I wouldn't expect a Jeep bumper to be sufficient for a full size rig or a FZJ 80. I can honestly state that these bumpers will hold up to the abuse you put it through.
