EXTREME POWER
At Traxxas, too much power is never enough! The durability of the VXL-8s™ is matched only by the sheer ferocity of its 8S 30+ volt 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.
-
ALL-METAL DRIVETRAIN
X-Maxx puts its massive power to the ground through an all-metal 8S driveline backed by the revolutionary Cush Drive™ system, high-strength extruded aluminum center shaft, and our strongest steel driveshafts ever. The Torque-Biasing Center Drive improves driveline durability and drives huge steel 4-gear differentials.
-
BELTED TIRES
X-Maxx’s belted Sledgehammer tires deliver game-changing stability and control whether you’re slinging mud or setting speed records. The wide, open-block tread design won’t clog up with dirt or debris and the lightweight belting maintains the tire’s shape for a larger contact patch, more grip, and responsive handling at any speed.
