This is the HPI Monster King Ford Bronco Big Kahuna RTR. The legend has evolved, and it’s bigger, tougher, and meaner than ever! The HPI Racing Monster King is here to take the crown, born from the DNA of two fan-favorite platforms: the Wheely King and the Crawler King. By combining the best of the Wheely-King and Crawler King into a single monster truck platform, we’ve created something special for Wheely-King fans!
Built around a refined version of the original Wheely King chassis, the Monster King boasts a new center gearbox with external slipper clutch, enhanced steering geometry, and new hex hardware for easier maintenance. Every change made with the performance, and fun in mind — from the Lock-Nut suspension mounts that banish E-clips forever, to the rugged new Tredz tires wrapped around wide 2.2” MT wheels.
Topping it all off is the fully licensed Ford Bronco 4400 bodyshell, an RC replica inspired by the real-life Big Kahuna truck, run by Shane England, with the help of RTR Vehicles and Vaughn Gittin Jr. Motorsports. Featuring a detailed interior, internal roll cage, and working LED light bars, this stunning body brings authentic Big Kahuna style and realism to the Monster King.
The Monster King Big Kahuna brings the spirit of the original Wheely King into a new era. Stronger, smoother, and packed with upgrades that fans will appreciate. With its tough solid-axle design, authentic details, and that unmistakable HPI fun factor, it’s ready to tear up any terrain in true monster truck style.
