We're Happy to offer you our latest creation from Primal RC the New 1/5 Scale Ready to Run 4X4 Mega Monster Truck! It's a real Gas powered 4-wheel drive solid-axle Monster Truck based on our Raminator Monster Truck. This New MEGA Monster Truck Features a new Classic Style Pickup Truck Body with a redesigned roll cage and New MEGA Mud Tires for a New Aggressive Look. These New Tires allow the overall track width of this truck to be 4.5 inches smaller than the Raminator's Monster Truck Tires so it's a little easier to fit places and drive around. Mechanically, everything else is the same between both new V3 trucks on the Primal Monster Truck platform.
