A bumper beam extension (10) for a bumper beam (12) having left and right bumper beam extensions and a method for manufacturing the bumper beam extensions to provide impact crush resistance. The bumper be ad extensions include an insert end (22) contoured and sized to fit in the end of the bumper beam and a main body portion (20) havi ng substantially a rearwardly facing saddle shape that includes an upper wing (24) and a lower wing (26) joined at a bight section (28). The main body portion (20) is blow molded to configure the bight section (28) to taper from a preselected distance from a forward wall (30) o f the main body portion (20) until it is face to face with the forward wall (30). For increased stiffness, the bumper beam (12) may be weld ed to a frame (14) of a vehicle. |
