Rancho RS5000X 0″ Rear Lift Shocks for 2004-2007 Buick Rainier

Part Number: RS55386

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to provide a significant upgrade over factory dampening. Engineered for the Buick Rainier and Oldsmobile Bravada, these shocks feature a unique progressive engagement valving system that minimizes harshness during initial impacts. This gas-pressurized solution is ideal for drivers seeking improved durability and a smooth, controlled street ride without compromising off-road capability.

Features

  • Cross-Tuned Technology: A specialized twin-tube valving system provides increased fluid capacity to ensure consistent performance under varying temperature ranges.
  • Progressive Engagement Valving: Custom-tuned internal discs provide a soft ride during low-velocity movement to ensure maximum comfort on paved surfaces.
  • Nitrogen Gas Pressurization: High-pressure gas charging provides a barrier against oil foaming to ensure fade-free performance during spirited driving.
  • Nitro-Carburized Piston Rod: A 16mm heavy-duty rod construction provides superior corrosion resistance and strength to ensure long-term seal integrity.
