Rancho RS5000X 1-2.5″ Rear Lift Shocks for 1988-2000 Chevy K2500 4WD

Part Number: RS55190

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to provide a significant upgrade in ride quality for your Chevy or GMC truck. These rear shocks are engineered to handle the increased demands of vehicles with 1 to 2.5 inches of lift, effectively eliminating the harshness often associated with aftermarket suspension. By balancing internal valving cycles, the RS5000X delivers a smooth street feel while maintaining the durability required for off-road excursions.

Features

• Cross-Tuned Technology: A unique valve base system provides a progressive engagement to ensure smooth transition between varying terrain types.
• Gas Pressurization: High-pressure nitrogen gas charge provides a reduction in oil foaming and aeration to ensure consistent damping performance under load.
• Heavy-Duty Body: A 2.25-inch twin-tube reserve tube provides increased oil capacity and dent resistance to ensure long-term reliability in harsh environments.
• Nitro-Carburized Piston Rod: The 16mm specialized rod coating provides superior corrosion resistance to ensure seal longevity and smooth shaft travel.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically lengthened and valved to work with vehicles that have already been modified with a 1 to 2.5-inch rear lift kit.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design is highly durable; if the outer tube is dented by a rock or debris, the inner working cylinder remains protected, allowing the shock to continue functioning.

Are these sold as a pair?
Yes, this specific SKU (2xRS55190) includes a pair of two rear shocks to complete the rear axle of your vehicle.
