Rancho RS5000X 1-2.5″ Front Lift Shocks for 1999-2007 GMC Sierra 1500 4WD

Part Number: RS55371

Summary: The Rancho RS5000X series utilizes a patented progressive engagement valving system to deliver a smooth, refined ride for your GMC Sierra or Yukon. Engineered for vehicles configured with 1-2.5 inches of front lift, these twin-tube gas pressurized shocks are designed to handle both daily commuting and rugged off-road trails. The cross-tuned technology balances low-speed comfort with high-speed control, effectively mitigating the harsh impacts often associated with leveled or lifted suspension geometries.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition of damping force to ensure consistent ride quality across varying terrain.
• Twin-Tube Gas Pressure: The 2.25-inch nitrogen-charged body provides increased fluid capacity to ensure cooler operating temperatures during extended use.
• Protective Boot: A heavy-duty black polyvinyl accordion boot protects the piston rod from debris to ensure long-term seal integrity and shock longevity.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically configured for vehicles that already have 1 to 2.5 inches of front lift height installed.

What is the benefit of the twin-tube design?
The twin-tube design is highly durable for off-roading; if the outer tube is dented by a rock, the inner working tube remains unaffected, allowing the shock to continue functioning.

Do these fit models with Electronic Suspension?
No, these are not compatible with GMC models equipped with Electronic Suspension (Z55) or Self Leveling Nivomat Suspension (ZW7).
