Part Number: RS55120

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for your GMC R3500. Utilizing a sophisticated gas-pressurization process, these shocks minimize aeration and foaming to maintain consistent damping performance under varying loads. The twin-tube design is specifically chosen for its ruggedness, offering an outer shell that protects the internal piston from trail debris and road hazards. Whether you are daily driving or hauling, these shocks deliver a refined, smooth street comfort without sacrificing heavy-duty control.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smooth transition between low and high-speed impacts to ensure maximum comfort on uneven surfaces.
• Gas Pressurization: High-pressure nitrogen gas charging provides a reduction in fluid cavitation to ensure consistent performance during rapid cycling.
• Twin-Tube Body: A 2.25-inch diameter reserve tube provides increased oil capacity and dent resistance to ensure long-term reliability in harsh environments.
• Nitro-Carburized Piston Rod: Heavy-duty hardened construction provides superior corrosion resistance to ensure the integrity of the internal seals.
