Traxxas Slash set the standard for durability, performance, and fun by which all other short course trucks are measured. Now Slash 4X4 comes outfitted with the BL-2s brushless power system for even more high-flying, fender-banging, action. The efficient BL-2s delivers all-day fun and endless torque for 4-wheel burnouts and ultra-responsive acceleration. Additionally, Slash 4X4 now comes standard with Traxxas’ Extreme Heavy Duty Upgrade Kit to take the most brutal punishment in stride.
