Summary: The Rancho RS9000XL series delivers industry-leading versatility for heavy-duty trucks through its globally recognized 9-position manual tuning system. Designed for the Chevy Silverado and GMC Sierra 2500HD/3500HD, these shocks allow drivers to instantly adjust damping levels to accommodate varying payloads and towing requirements. Whether navigating empty highways or hauling maximum GVWR trailers, this Tier 2 adjustable solution provides the precise control needed to eliminate sway and optimize ride quality.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect balance between street comfort and heavy-duty towing stability.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during sustained heavy hauling.
• Nitrogen Gas Charged: High-pressure gas integration provides a reduction in aeration and foaming to ensure consistent damping performance under aggressive road conditions.
• Fluon-Banded Piston: A specialized piston coating provides a consistent seal between the piston and pressure tube to ensure rapid response to road irregularities.

Frequently Asked Questions

How do I adjust the settings on these shocks?
Each shock features an external 9-position knob located at the base of the shock body that can be turned by hand to increase or decrease firmness.

Will these shocks lift my Silverado or Sierra?
No, these shocks are configured for vehicles at a 0-inch lift height and are designed to replace factory-length dampers.

What setting should I use for towing?
Higher settings (7-9) are recommended for heavy towing to increase stability, while lower settings (1-3) are ideal for an unloaded, smoother ride.
