RC Solutions cage protects everything on the truck - engine, radio, fuel tank, etc. The roll cage also supports the body, so bodies last much longer. Cartwheels and flips no longer scrape up the cylinder head and break body mounts, shock towers, and fuel tanks. With the cage on, there is still good access to radio boxes, pull starters and filters. Bodies fit with minor modifications. Cages for the all T/E Maxx trucks can use the original bumpers, but are designed together with our spring-steel skid plates to eliminate the conventional bumpers. This roll cage will NOT fit the original T-Maxx 3.3, Traxxas part #4909. The T-Maxx Ext. Chassis Roll Cage is available in silver, black, or blue.
