An upgrade to the factory leaf spring suspension, R4Tech increases axle control during acceleration and braking for improved torque management and reduced wheel hop. The design allows the suspension to move at all load conditions, therefore isolating and absorbing road impact for passengers and cargo alike. Plus, less steel in the system reduces weight in the vehicle and improves fuel economy.
