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

Part Number: RS55268

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for vehicles equipped with a 4-inch lift. Utilizing a sophisticated twin-tube design, these shocks are specifically tuned to mitigate the harshness often associated with torsion bar suspensions. By integrating a patented Progressive Engagement Valving system, the RS5000X delivers a smooth street ride while maintaining the ruggedness required for off-road excursions.

Features

• Progressive Engagement Valving: Custom-tuned internal shim stacks provide a gradual transition of fluid to ensure reduced body roll and improved stability during cornering.
• Gas Pressurization: High-pressure nitrogen gas charge provides a consistent damping force to ensure minimized aeration and shock fade during spirited driving.
• 16mm Nitro-Carburized Rod: A heavy-duty hardened piston rod provides increased structural integrity to ensure long-term resistance against scuffs and corrosion.
• Double-Welded Mounts: Reinforced loop-style end mounts provide maximum strength at critical stress points to ensure the shock remains secure under heavy articulation.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically valved and extended in length to function correctly with a vehicle that already has a 4-inch suspension lift installed.

Is the RS5000X better for street or off-road?
The RS5000X is a versatile hybrid shock designed for daily drivers that see occasional trail use, offering excellent vibration dampening on pavement and durability in the dirt.

Do I need to purchase boots separately?
No, this set includes Rancho’s signature red protective boots to keep debris away from the piston seals.
