Rancho RS5000X 4″ Front Lift Shocks for 2004-2008 Infiniti QX56

Part Number: RS55773

Summary: The Rancho RS5000X series features a cross-tuned twin-tube design engineered to improve both on-road comfort and off-road durability. Specifically configured for vehicles with a 4-inch lift, these shocks utilize a unique progressive engagement valving system to minimize harshness during initial impacts. This setup provides a balanced ride for your Infiniti QX56, ensuring the suspension remains composed over varied terrain while maintaining a smooth street feel.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smooth transition between damping forces to ensure consistent ride quality on uneven surfaces.
• Twin-Tube Gas Pressure Design: The 2.25-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures and consistent damping performance.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod construction provides superior corrosion resistance and structural integrity to ensure long-term reliability in harsh environments.
• Polyurethane Bushings: High-density mounting material provides reduced vibration transfer to ensure a quieter cabin and more precise suspension response.
