Back to the grill guard.... (aka pushbar with brushguards). Westin's uses bolt on clamps to the bumper and attaches to the frame using the two bolts for the tow hooks. When I put the body lift in and raised the front bumnper, I made a set of brackets that it bolts onto. Most of the support of anything your going to push is going to come from the bumper. Just be sure to use stainless hardware.
