Rancho RS5000X 0″ Rear Lift Shocks for 2004-2008 Infiniti QX56

Part Number: RS55396

Summary: The Rancho RS5000X series leverages advanced CrossTun technology to provide a significant upgrade over factory damping for your Infiniti QX56 or Nissan Armada. Designed as a Tier 4 twin-tube shock, it features a unique valving system that minimizes foam and cavitation to maintain consistent performance. This shock is engineered for durability and dent resistance, delivering smooth street comfort and reliable control for stock-height SUVs.


Features

  • Progressive Engagement Valving: A custom-tuned compression disk provides a gradual transition to firm damping to ensure a smooth ride over harsh road irregularities.
  • Gas Pressurization: High-pressure nitrogen gas charge provides reduced aeration and foaming to ensure consistent hydraulic performance during spirited driving.
  • Double-Welded Mounts: Reinforced loop-style mounts provide increased structural integrity to ensure long-term durability under heavy load conditions.
  • Protective Boot: A heavy-duty polyvinyl accordion boot provides a physical barrier for the piston rod to ensure the oil seal remains free from debris and contaminants.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks are configured for a 0-inch lift height and are designed to replace factory-length shocks without changing the vehicle’s ride height.

Do these work with the factory air leveling system?
No, these shocks are specifically designed for models excluding Auto Rear Leveling. They are not compatible with vehicles using factory air-ride systems.

What is the benefit of the RS5000X gas charge?
The nitrogen gas pressurization prevents the oil from foaming (aeration), which ensures that the valving remains precise and effective even during repetitive cycling on rough roads.
