This product is a CNC machined aluminum rear bumper mount frame brace designed to strengthen the rear chassis section of scale crawler vehicles. The rigid one-piece 6061 aluminum construction replaces the factory plastic rear bumper cross-member to improve frame rigidity and durability during trail driving. Precision machining maintains proper spacing between the frame rails and bumper posts for secure mounting. A black anodized finish protects the aluminum from corrosion while providing a clean scale appearance. The brace installs as a direct replacement for the stock Axial rear bumper mount used on SCX10 II vehicles.
