Rancho RS5000X 0-2″ Rear Lift Shocks for 1969-1980 GMC K1500 4WD

Part Number: RS55118

Summary: The Rancho RS5000X series utilizes a sophisticated twin-tube gas pressurized design to provide exceptional durability and ride comfort for your GMC K1500 or Toyota Land Cruiser. Featuring Rancho’s Progressive Engagement Valving, these shocks are engineered to reduce initial harshness while maintaining control during off-road excursions. Configured for 0-2 inches of rear lift, they offer a significant upgrade over stock dampers by minimizing aeration and shock fade through increased fluid capacity and a pressurized nitrogen charge.

Features

• Progressive Engagement Valving: A custom-tuned internal shim stack provides a soft ride during initial travel to ensure smooth street comfort and reduced vibration.
• Gas Pressurized Twin-Tube: The nitrogen-charged 2.25-inch body provides consistent damping force and prevents oil foaming to ensure reliable performance in high-duty cycles.
• Hardened Nitro-Carburized Rod: The 16mm heavy-duty piston rod provides superior scuff resistance and structural integrity to ensure long-term seal protection.
• Protective Boot: The included red polyvinyl accordion boot provides a physical barrier against debris and moisture to ensure the longevity of the polished chrome rod.

Why Choose This Product?
