This bumper was designed specifically to fit the Grave Diggers frame! Complete with steel backing/mounting brackets this bumper is SOLID! Quite literally. 
Most of our bumpers are designed to have some give and as we tell you upfront they are not bullet proof. We believe that it’s better to break the bumper than the kid! But this theory has become an issue on the grave diggers as the metal frame absorbs zero shock and blows apart the bumper. So we had to create “The Hammer”! A solid plastic bumper that still conforms to all plastic only rule sets! But will hold up to all of those little Mad Dog drivers! We have incorporated additional connection areas, thicker top plate, and a larger foot print for the brackets! (Included). This bumper weighs in at 12lbs! And 26” long. 
PLEASE NOTE: This is a longer lead time item. While I try to keep one or two in stock, these bumpers take 48 hours to create from start to ship.
