Purpose Built

The TRX-4 Sport combines the unbeatable ground clearance and driving dynamics of Traxxas portal axles, sticky Canyon^® Trail tires, and a lightweight pickup truck body for a leaner, performance-focused new TRX-4. The Sport’s unique bumpers, wheels, and body were designed for increased climbing versatility.
