The StealthR XF symbolizes the continued progression of the Element RC brand. We took many of the notes and design features we learned from the Stealth X and refined them into a forward-motor setup. The new design moves the motor forward to help keep the weight over the front wheels while maintaining a lower center of gravity. This upgraded pre-assembled transmission comes equipped with new 18% overdrive gears, Factory Team Slipper lockout, and ball bearings for ultra-smooth operation. The Stealth XF Transmission Set comes pre-assembled and greased from the factory and includes: #42333 Enduro SE FT Stealth XF Slipper Lockout #91563 FT Bearings, 10x15x4mm Plastic Stealth XF upper case gears #42338 Stealth XF 18% Overdrive gears (55T/25T) New #42339 Stealth XF Overdrive Outdrives #41090 LP SHCS motor screws
