Part Number: RS55151 / RS55118

Summary: The Rancho RS5000X series utilizes a cross-tuned twin-tube gas pressurized design to enhance the ride quality of your classic Chevy K-20 or GMC Suburban. This shock set is engineered to provide a balance between rugged off-road durability and smooth street comfort by utilizing a progressive engagement valving system. Whether you are maintaining a stock height or have a 2-inch lift, these shocks are configured to handle the increased demands of a 4WD drivetrain while mitigating harsh impacts. The result is a more controlled driving experience that reduces body roll and improves handling on varied terrain.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smoother transition during suspension travel to ensure consistent ride quality over uneven surfaces.
• 2.25-inch Twin-Tube Body: A large capacity fluid reservoir provides increased oil volume to ensure cooler operating temperatures during extended use.
• Nitrogen Gas Pressurization: 150 PSI gas charge provides immediate response and minimizes aeration to ensure fade-free performance.
• Nitro-Carburized Piston Rod: A 16mm heavy-duty rod construction provides superior scuff and corrosion resistance to ensure long-term seal integrity.

Frequently Asked Questions

Will these shocks lift my Chevy K-20?
No, these shocks do not create lift. They are specifically configured for vehicles at factory height or with up to 2 inches of suspension lift to ensure the piston operates within its optimal range.

Can these be used on models with the factory Quad Shock option?
No, these are designed for standard suspension configurations and exclude models equipped with the O.E. Quad Suspension setup.

What is the benefit of the twin-tube design for my Suburban?
The twin-tube design provides excellent durability; the outer tube protects the inner working tube from dents and debris, ensuring the shock continues to function even in harsh environments.
