Part Number: RS55377

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for your heavy-duty workhorse. Featuring a sophisticated twin-tube design, these shocks utilize a unique Progressive Engagement Valving system to minimize harshness during initial impacts. Specifically configured for 0-inch lift heights on the Chevy Silverado 3500HD Chassis Cab, they provide the rugged dent resistance and smooth street comfort required for demanding commercial and towing applications.

Features

• Progressive Engagement Valving: Custom-tuned internal valving provides a smoother transition between low and high-speed impacts to ensure consistent control on varied road surfaces.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a faster response rate and reduced aeration to ensure fade-free performance during heavy-duty hauling.
• Twin-Tube Body: A 2.25-inch diameter reserve tube provides increased oil capacity and physical protection to ensure the inner pressure tube remains functional even if the outer shell is dented.
• 16mm Nitro-Carburized Rod: The heavy-duty piston rod provides superior scuff resistance and corrosion protection to ensure long-term seal integrity in harsh environments.
