Summary: The Rancho RS9000XL series provides the ultimate level of ride control for GMC Yukon XL 1500 owners equipped with the Z55 Electronic Suspension. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow you to bypass the factory electronic damping in favor of custom-tuned performance. Whether you are navigating smooth highways or rugged trails, this Tier 2 adjustable shock provides the versatility to switch from a soft, comfortable ride to a firm, high-performance setting in seconds. Engineered specifically for vehicles with 4-inch lift systems, these shocks ensure your leveled or lifted SUV maintains superior stability and handling.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the driver can customize ride stiffness for towing, hauling, or off-road use.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty cycles.
• Nitrogen Gas Charged: High-pressure gas charging provides a consistent response by minimizing air-to-oil mixture to ensure reduced fade and aeration.
• Protective Boot: An included heavy-duty bellows boot provides a physical barrier for the oil seal to ensure longevity against road debris and contaminants.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a 9-position manual knob located at the base of the shock body. Simply turn the dial to your desired setting, with 1 being the softest and 9 being the firmest.

Will these shocks work with my factory electronic suspension?
These shocks are designed for Z55-equipped vehicles that have been lifted 4 inches using specific Rancho systems. They replace the electronic function with manual adjustability.

Do these shocks create the 4-inch lift?
No, these shocks do not create lift. They are specifically valved and length-configured for vehicles already equipped with a 4-inch suspension lift kit.
