Fits the REVO 3.3 extended chassis. Our objective for the REVO Roll Cage was a strong, light weight cage that would perfectly compliment the hi tech REVO. The REVO chassis has a compact layout, leading to some design challenges. Finding attachment points for the cage was the biggest challenge, as there are no shock towers or other conventional landmarks to work with. Our solution was to use machined parts for the first time, resulting in a cage as strong and light as anything we have produced. Like our other cages, the REVO cage is made of interlocking 1/8" 6061 T6 aluminum to form a strong shell around the truck. It is so strong an adult can stand on it. The cage protects everything on the truck - engine, radio, fuel tank, etc. It also supports the body, so bodies last much longer. There remains good access to the radio boxes, fuel tank and filter. It works with the stock bumpers and skid plates. Stock and aftermarket bodies fit with just minor modifications. This cage is extended to fit the REVO 3.3 and will not work with a regular REVO.
