The Rancho RS5000X gas-pressurized shock absorber is engineered to provide a significant upgrade in handling and control for heavy-duty trucks and SUVs. Utilizing Rancho's exclusive Cross Tuned technology, these shocks feature a unique valving system that manages both the rebound and compression phases to improve stability on and off-road. The twin-tube body is nitrogen-charged to 150 PSI to minimize aeration and foaming, ensuring consistent damping performance even during heavy use.

• All-Weather Performance: Filled with specialized fluid designed to maintain viscosity in internal temperatures ranging from -40 to 248°F.
• Durable Seals: Low-friction, self-lubricating seals retain gas and oil for quicker rebound and smoother compression.
• Enhanced Protection: Includes a polyvinyl protective boot and double-welded loops at high-stress mounting points.
