Rancho RS5000X 1-2.5″ Front Lift Shocks for 2002-2006 Chevy Avalanche 1500

Part Number: RS55371

Summary: The Rancho RS5000X series provides a significant upgrade in ride quality and durability for your leveled or lifted GM truck. Engineered with a large 2.25-inch body, these twin-tube gas-pressurized shocks offer increased fluid capacity to maintain cooler operating temperatures during heavy work or trail use. Specifically configured for 1-2.5 inches of front lift, they provide the necessary travel and damping control to eliminate the harshness often associated with torsion bar adjustments.

Features

• Crossed Landscape Valve System: A specialized progressive valving circuit provides specific engagement for on and off-road environments to ensure a smooth, controlled ride in all conditions.
• 2.25-inch Shock Body: An oversized outer tube provides increased oil capacity to reduce heat buildup and ensure consistent damping performance.
• Nitrogen Gas Pressurization: A pressurized gas charge minimizes air-to-oil mixture (aeration) to ensure immediate response and fade-free performance.
• Protective Boot Included: A durable poly-vinyl accordion boot provides a physical barrier for the piston rod to ensure long seal life against road debris.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically configured for vehicles already equipped with 1-2.5 inches of front lift to ensure proper travel and prevent bottoming out.

Do these fit models with Autoride?
No, these are designed to replace standard shocks and are not compatible with vehicles equipped with Electronic Suspension (Z55) or Nivomat Self-Leveling (ZW7) systems.

What is the benefit of the larger shock body?
The 2.25-inch body holds more oil than standard replacement shocks, which helps dissipate heat more effectively and prevents the shock from “fading” or becoming soft during heavy use.
