The Traxxas TRX-4® Tactical Unit is a rapid-response vehicle designed to charge into practically any situation, ready for fun and adventure. Its lightweight body offers high-speed agility and superior technical crawling. Where other trucks fear to go, the Tactical Unit charges ahead full throttle!
The secret to the Tactical Unit’s extreme all-terrain capability lies underneath its tough camouflaged body. Exclusive portal axles deliver maximum ground clearance and virtually eliminate torque twist. Remotely-actuated front and rear differentials unlock for all-out speed and lock for rock-gripping traction on treacherous surfaces. The high/low range transmission transforms the Titan motor’s power into incredible torque in low gear or blazing speed in high gear. Built the Traxxas way, the Tactical Unit is tough, powerful, and ready to take on your wildest adventures.
