Stainless steel rear bumper with post, no basket, no diagonals. Post helps avoid push truck (and other cars) from jumping the bumper, and getting into the tank. No diagonals makes this one of the lightest bumpers around. Polished to perfection. CNC bent and jig built for quality and exact fit.Remember, ounces equal pounds. Pounds equal tenths. If you race at a track or with a series that qualifies, one tenth might mean the difference between a spot in the dash or a charge. Fits most chassis.
