Made from interlocking .090? T6 aluminum to form a strong shell around the truck. Most of our roll cages can withstand the weight of a full grown adult. This cage protects everything on the truck ? engine, radio, fuel tank, etc. It also supports the body, so bodies last much longer. RC Solutions has replaced the plastic chassis to aluminum to provide additional strength to the Nitro Rustler Stadium Truck. The plastic servo has also been replaced with an aluminum mount for added protection. There is good access to the radio box, pull starter and filters. Bodies fit with minor modification. Discontinued item. Limited quantites remain.
