Rancho RS5000X 2.5-4″ Lift Shocks for 1981-1991 Chevy Blazer 4WD

Part Number: RS55001

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to provide exceptional durability and ride quality for lifted GMC and Chevy SUVs. Engineered to handle the increased demands of a 2.5-4″ lift, these shocks feature a unique valving system that minimizes foam and cavitation. The result is a smooth, controlled street ride that remains rugged enough for off-road excursions and heavy-duty utility.

Features

• Progressive Engagement Valving: A custom-tuned compression disk provides a gradual transition to firm damping to ensure consistent comfort during varying road conditions.
• Gas Pressurization: High-pressure nitrogen gas charge provides a reduction in aeration and foaming to ensure fade-free performance in demanding environments.
• 16mm Nitro-Carburized Rod: The heavy-duty hardened piston rod provides increased structural rigidity to ensure long-term resistance against scuffs and corrosion.
• Double-Welded Mounts: Reinforced loop-style end mounts provide maximum strength at high-stress points to ensure reliability during off-road articulation.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically configured for vehicles already equipped with a 2.5-inch to 4-inch suspension lift kit.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design provides an outer reserve tube that protects the internal pressure tube from dents, ensuring the shock remains functional even if the outer body is damaged off-road.

Does this include all four shocks?
Yes, this specific SKU includes a full set of four shocks (two front and two rear) for a complete vehicle overhaul.
