Summary: The Rancho RS5000X series utilizes a CrossQuest progressive engagement valving system to deliver a refined ride for your heavy-duty truck. Designed specifically for GMC Sierra 2500HD and 3500HD models with 5 to 6 inches of front lift, these twin-tube gas-pressurized shocks provide exceptional durability and dent resistance. This configuration ensures smooth street comfort while maintaining the ruggedness required for off-road environments and heavy work cycles.

Features

• Progressive Engagement Valving: Custom-tuned internal valving provides a smooth transition between low and high-speed impacts to ensure consistent ride quality on varied terrain.
• Gas Pressurization: High-pressure nitrogen gas charge provides a reduction in oil foaming and aeration to ensure fade-free performance during spirited driving.
• Twin-Tube Design: A 2.25-inch diameter reserve tube provides increased oil capacity and mechanical protection for the internal pressure tube to ensure long-term reliability in harsh conditions.
• Nitro-Carburized Piston Rod: A heavy-duty hardened rod construction provides superior corrosion resistance to ensure a long seal life.

Frequently Asked Questions

Will these shocks lift my GMC Sierra?
No, these shocks do not create lift. They are specifically valved and sized to function correctly on vehicles that already have a 5-6″ lift kit installed.

What is the benefit of the twin-tube design?
The twin-tube design is highly durable for off-roading; if the outer shell is dented by a rock, the inner pressure tube remains functional, allowing you to get home safely.

Are these sold as a pair?
Yes, based on the SKU configuration, this package includes two front shocks to cover both the driver and passenger sides.
