Rock Rey Kit: 1/10 4WD Rock Racer

Build the Losi Rock Rey any way you want. It comes with a robust chassis and option parts ready to dial up the scale looks and performance. You have the freedom to do what you want without having to throw away stock electronics.

At a Glance

With the Losi® Rock Rey Kit, option parts come standard so you can customize the vehicle how you want. You have complete freedom to accessorize and hop up your vehicle to your liking. With a new roll cage that resembles full-scale rock racers, this basher is ready to go head-to-head with the best. Its new front-end geometry adds the needed handling for rock racing while taking advantage of the Baja Rey's rear-loading battery and bottom-loading motor. The Rock Rey is most at home in rocky terrain-the rougher the better. So go ahead let it rip.
