2011 Nitro Doorslammer (COLOR SHIFTERS) HOT WHEELS (LOOSE) - USADO

From 2008 to 2012, regular castings featured a plastic base with a flip-out, anti-wheelie bar that locks open or closed with a small plastic tab. In 2013, the casting changed so that the anti-wheelie bar is shorter, molded into the base and does not move. However, all Color Shifters versions from 2008 to present have a metal base and the wheelie bar molded into the base as if it were folded. Versions with the shorter wheelie bar are not compatible with kicker loops as the wheelie bar can get stuck on the kicker.
