The Stampede 4X4 VXL is engineered like no other to turn extreme power into extreme monster truck fun! Traxxas Stability Management® (TSM) lets you experience Stampede’s extreme power, speed, and acceleration by making it much easier to control on slippery surfaces such as loose dirt, smooth concrete, and even ice and snow. The efficient, low-mass drivetrain is totally optimized for the brutal torque of Velineon brushless power, and following the legacy of the Stampede name, this 4X4 is overbuilt and Traxxas Tough to withstand all the 4-wheel drive monster mayhem you can dish out. The patented adjustable wheelie bar is required equipment as Stampede 4X4 launches hard, sending the front wheels soaring for the sky. You’re in full control with the Traxxas TQi 2.4GHz radio system and the superior handling of fully independent suspension and smooth bellcrank steering. Choose a 7-cell NiMH battery (sold separately) for 35+mph speed or install a 3S LiPo pack, and Stampede 4X4 shatters the speedometer with 60+mph speed! It’s brushless done the Traxxas way: brutally fast and easy to use.
