Take on anything

Gear up for intense off-road and car-crushing action with the Wheely King 4x4! The Wheely King 4X4 is a true-to-scale monster truck that features full-time 4WD for maximum traction that allows it to go anywhere. From car-crushing stadium monster truck action to rock crawling in the mountains, the Wheely King 4X4 can do it all. And of course, awesome wheelie action is available with a pull of the trigger!

With custom tuned weight distribution and a rear wheelie bar, easy controlled wheelies are part of the action every time you! Watch it drive long stretches with its wheels in the air and pop a wheelie out of every turn for wheelie good fun!

If wheelies aren't your thing, all it takes is a few simple modifications to take your Wheely King 4X4 to the next level: rock crawling! With waterproof electrics you truly can take it anywhere!

The Wheely King 4X4 is great for the show-and-go crowd, too: fat chrome wheels hold 5.4" all-terrain Mud Thrasher monster truck tires, and the Twin Vertical Plate (TVP) chassis features a super cool tube design that looks just like the real monster trucks you've enjoyed watching! Front and rear solid axles feature pivot joints and a realistic looking multi-link monster truck suspension for easy driving and control!

It's not just about its good looks, however - the Wheely King 4X4 lives up to its name from the second you pull the trigger! With its strong 540-size motor and solid-axle 4WD drive train, the Wheely King 4X4 is a joy to drive around tight, twisty terrain or down the street! Finally, the 2.4GHz radio system and waterproof electronics let you confidently control the Wheely King in any kind of terrain or weather conditions!
