The crossbars are key. This is what makes our gaurds great and different, and not just like the others. These link the 2 guards together, so that when one pulls away from the frame, the link pulls the other guard INTO the frame. Pulling INTO the frame, keeps the 2 small radiator guard securing bolts, from easily snapping off. These crossbars easily quadrubile the strength of you guards and you radiators protection.
