3 piece mount allows direct mounting of a single electric motor in the stock Nitro Revo motor mount location. The lower plate attaches directly to the chassis with included screws. The front motor mount and rear motor support attach to the lower mount plate for a light weight, rigid and attractive mount. The front motor mount plate has adjustment built in, as does the rear support. We recommend the Traxxas Revo chassis brace (TRA 5361) for a more rigid platform with this motor mount.
