Rancho RS5000X 2.5-4″ Rear Lift Shocks for 1992-1994 Chevy Blazer 4WD

Part Number: RS55190

Summary: The Rancho RS5000X series leverages a patented Progressive Engagement Valving system to deliver a smooth, controlled ride for lifted Chevy and GMC SUVs. Designed specifically for vehicles with 2.5 to 4 inches of rear lift, these twin-tube shocks excel at absorbing harsh impacts while maintaining excellent street manners. The gas-pressurized design minimizes fluid aeration, ensuring consistent damping performance whether you are navigating daily commutes or weekend trails.

Features

• Progressive Engagement Valving: Custom-tuned internal shim stacks provide a soft ride during initial travel and firmer control during high-velocity impacts to ensure superior handling in varied terrain.
• Twin-Tube Gas Pressure: A 150 PSI nitrogen gas charge provides a consistent damping response to ensure reduced foaming and shock fade.
• 16mm Nitro-Carburized Rod: The heavy-duty hardened piston rod provides increased structural rigidity to ensure long-term durability against rock chips and corrosion.
• Protective Boot: Included red polyvinyl accordion boot provides a physical barrier for the oil seal to ensure debris does not compromise the internal components.

Why Choose This Product?

• Engineering Advantage: Rancho’s cross-tuned technology optimizes the relationship between the piston and the base valve for a more precise damping curve than standard replacement shocks.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically long-travel dampers configured for vehicles that already have a 2.5-inch to 4-inch suspension lift installed.

Are these shocks sold as a pair?
Yes, this SKU (2xRS55190) includes two rear shocks to complete the installation for one axle.

What is the benefit of the RS5000X gas-pressurized design?
The nitrogen gas charge keeps the shock oil under pressure, which prevents air bubbles from forming. This ensures the shock maintains its damping force even during rapid movement on rough roads.
