About the Big Rock V4
Clipless Body
Gone are the days of body clips sticking out and taking away from the scale detail that RC monster trucks can have. Arrma equipped this vehicle with a hidden, clipless body system. Simply press the tabs at the front and rear of the truck and lift up. Large side guards are close-fitting to the body to help ensure dirt and rocks keep out of the chassis.
Chassis & Suspension
The front and rear independent suspension combined with oil-filled, coil-over shocks soak up rough terrain. Adjustable turnbuckles allow you to fine tune the suspension for your driving style. Forthe drivetrain, the Big Rock is equipped with metal gear differentials, front, center, and rear, and durable splined driveshafts. The bearing-supported center driveshaft ensures smooth power transfer from the motor to the front and rear differentials.
