Take your Cummins to the next level of stance and control of a 4-Link Long-arm suspension while sending it off to the moon with a full 6" of an increased ride height! This suspension system features 6" progressive Pro-Ride Coil Springs and solid steel upper long arms and thick tubular lower long control arms.
