Unrelenting 4X4 power, mammoth size, and award-winning innovation make X-Maxx the ultimate monster truck. With 30+ volts of extreme 8S power, X-Maxx defies physics, unleashing jaw-dropping acceleration and 50+mph speeds. Engineered to conquer the most extreme terrain and take brutal real-world punishment in stride, X-Maxx is the definition of Traxxas Tough
MODEL 77086-4: Fully assembled and Ready-To-Race with TQi 2.4GHz radio system with Traxxas Stability Management, VXL-8s Brushless Power System, and ProGraphix painted body.
At the end of the day, size always wins. X-Maxx plows over obstacles and muscles through extreme terrain that leaves lesser trucks stranded. Mammoth 8-inch tall tires, long-arm suspension, and huge ground clearance dwarf the surroundings for virtually unstoppable monster truck fun.
At Traxxas, too much power is never enough! The durability of the new VXL-8s is matched only by the sheer ferocity of its 8s 30+ volt dual LiPo muscle. The speed-tuned 1200XL Big Block™ motor propels X-Maxx with brutal authority and exacting quickness that warps your senses. No matter what you have driven in the past, nothing will prepare you for X-Maxx.
X-Maxx puts the power to the ground through tough all-steel drivetrain gears, the revolutionary Cush Drive system, and our strongest driveshafts ever. The all-new Torque-Biasing Center Drive improves driveline durability and drives larger module ring and pinion gears on the toughest differentials we have ever produced
