Rancho RS5000X 4″ Rear Lift Shocks for 1999-2006 Chevy Silverado 1500 4WD

Part Number: RS55269

Summary: The Rancho RS5000X series utilizes an innovative CrossFlow technology to provide a versatile ride for both daily commuting and off-road excursions. Specifically configured for vehicles with a 4-inch rear lift, these shocks feature a large 2.25-inch reserve tube to increase oil capacity and reduce internal heat. By utilizing a progressive engagement valving system, these shocks maintain smooth street comfort while providing the necessary damping force during aggressive suspension cycling.

Features

• CrossFlow Technology: A unique valving system provides a custom-tuned damping experience to ensure consistent performance across varied terrain.
• 2.25-inch Reserve Tube: An increased fluid capacity provides superior heat dissipation to ensure fade-free performance during heavy hauling or off-road use.
• Nitrogen Gas Pressurization: A high-pressure gas charge provides a quicker response rate to ensure the tires maintain contact with the road surface.
• Nitro-Carburized Piston Rod: A 16mm heavy-duty rod provides exceptional scuff and corrosion resistance to ensure long-term seal integrity.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically sized and valved to work with a vehicle that already has a 4-inch rear lift kit installed.

What is the benefit of the included shock boots?
The protective boots shield the nitro-carburized rod from road debris, salt, and mud, which extends the life of the internal seals.

Are these shocks sold as a pair?
Yes, based on the SKU configuration, this package includes 2 rear shocks for a complete axle installation.
