Summary: The Rancho RS9000XL series provides industry-leading adjustability for drivers who demand total control over their vehicle’s ride profile. Featuring a 9-position manual tuning knob, these shocks allow you to instantly transition from a soft street ride to a firm setting optimized for towing or heavy hauling. Designed for the Chevy K2500 and GMC Yukon, these nitrogen-gas charged shocks deliver consistent performance by reducing aeration and shock fade during strenuous use.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping force to ensure the perfect ride quality for any terrain or load requirement.
• Nitrogen Gas Charging: Pressurized gas stabilization provides a reduction in fluid aeration to ensure consistent damping performance under high-heat conditions.
• Large Shock Body: A heavy-duty 2.75-inch diameter body provides increased fluid capacity to ensure cooler operating temperatures during off-road use.
• Polyurethane Bushings: High-density polyurethane material provides enhanced durability and pivot resistance to ensure long-term mounting integrity.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
These shocks feature a manual knob located at the base of the shock body. Simply turn the dial to your desired setting (1 for softest, 9 for firmest).

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

Are these shocks nitrogen charged?
Yes, they are nitrogen-gas pressurized to minimize foaming and ensure the shock responds rapidly to road imperfections.
