Rancho RS5000X 0-2″ Rear Lift Shocks for 1969-1986 GMC K2500 4WD

Part Number: RS55118

Summary: The Rancho RS5000X series utilizes a patented progressive rebound and compression disc system to enhance the ride quality of your GMC K2500. This twin-tube gas-pressurized shock is engineered to handle both highway stability and off-road durability, providing a versatile solution for vehicles with up to 2 inches of rear lift. By reducing aeration and shock fade, these units ensure consistent damping performance under heavy-duty cycles or weekend trail use.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound discs provide a soft ride during initial travel to ensure maximum comfort on paved surfaces.
• Twin-Tube Gas Pressure: A 150 PSI nitrogen gas charge provides a consistent damping force to ensure reduced aeration and foaming.
• Heavy-Duty Body: A 2.25-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during sustained use.
• Nitro-Carburized Piston Rod: The 16mm hardened rod provides superior scuff resistance to ensure long-term seal integrity and corrosion protection.
