Part Number: RS55377

Summary: The Rancho RS5000X series utilizes a sophisticated twin-tube gas pressurized design to enhance the ride quality of your GMC Sierra 3500HD. Engineered with Rancho’s exclusive Progressive Engagement Valving, these shocks are specifically tuned to reduce harshness during initial impacts while maintaining firm control during heavy-duty maneuvers. This complete set provides a durable and smooth street-focused solution for trucks maintained at factory ride height.

Features

• Progressive Engagement Valving: Custom-tuned internal shim stacks provide a smooth transition between low and high-speed damping to ensure consistent comfort across varying road surfaces.
• Twin-Tube Gas Pressure: A 150-PSI nitrogen gas charge provides a responsive damping force to ensure minimized aeration and foaming.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod construction provides increased scuff resistance and protection against corrosion to ensure long-term seal integrity.
• Protective Boot: Included red polyvinyl accordion bellows provide a physical barrier against debris and road salt to ensure the longevity of the shock rod and oil seal.
