Rancho RS5000X 2.5-4″ Front Lift Shocks for 1988-1999 GMC K1500 4WD

Part Number: RS55001

Summary: The Rancho RS5000X series utilizes a patented Progressive Engagement Valving system to provide a significant upgrade for your GMC K1500’s front suspension. Engineered specifically for vehicles with 2.5 to 4 inches of lift, these twin-tube shocks are designed to minimize harshness while maintaining control during off-road excursions. The gas-pressurized design provides consistent performance and durability, ensuring a smooth street ride and rugged reliability on the trail.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition of fluid to ensure a smooth ride without sacrificing high-speed control.
• Twin-Tube Body: A 2.25-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures and dent resistance.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod construction provides a hardened surface to ensure long-term seal integrity and corrosion resistance.
• Gas Pressurization: 150 PSI Nitrogen gas charging provides a reduction in aeration and foaming to ensure consistent damping performance in varied terrain.
