This is the JConcepts "Scalpel" Speed Run Illuzion Body and is intended for use with the Traxxas Slash 4x4 and Rally vehicles. The Slash 4x4 has the DNA to be an absolute beast of an on-road vehicle and the JConcepts Scalpel speed-run body and front bumper conversion allows you to turn your Slash 4x4 into an insane speed-run machine. Looking straight into the headlights you can tell right away something is different about the Scalpel. A menacing look from the front-end highlighted by a dramatic chin-spoiler, the front-end is built for speed and direction. Large fenders allow plenty of clearance for the 2.8” G-Locs tires and the extremely low roof-line cuts like a knife. A shallow bed area gives the Scalpel a truck-like appearance while maintaining that all inclusive speed-line structure. Finishing off the body is clean and smooth with the inclusion of grill, headlight, taillight and miscellaneous logos that make the Scalpel look the part.

Making the conversion:
Converting the Slash 4x4 to the Scalpel speed-run vehicle requires the Scalpel body and front bumper conversion (JCI2173), JConcepets G-Locs tires (JCI3056-00) and Rulux wheels (JCI3340B). The assembly is simple and takes only minutes to complete. First, remove the stock bumper assembly and replace with the speed-run accessories and foam bumper. Make small changes to suspension set-up to limit down and up travel per instructions. Detail, paint and trim Scalpel body. Prep, mount and glue JConcepts 2.8” G-Locs tires onto 2.8” Rulux wheels and secure to the vehicle. Locate, mark and ream the body mount locations and drop Scalpel body into place. Hit your favorite closed circuit for the wildest speed-runs imaginable. Plus, the Traxxas Rally can also be easily converted to this high-performance speed run vehicle with very minimal steps. Follow the introduction and step-by-step video here for the best and most efficient speed run conversion available from JConcepts.

Great looking body. The pull was a bit thin on the lower right side.
