Summary: The Rancho RS9000XL series delivers industry-leading versatility for heavy-duty trucks and SUVs. Featuring a manually adjustable 9-position damping system, these shocks allow drivers to instantly tune their ride quality to match changing loads or terrain. Whether you are daily driving or hauling heavy equipment, this Tier 2 adjustable shock provides the perfect balance of street comfort and off-road control for vehicles configured with 5 to 6 inches of front lift.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the driver can transition from a soft street ride to firm control for towing.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure consistent cooling and reduced fade during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas optimization provides a faster response rate to ensure the tires maintain contact with the road surface on uneven terrain.
• Protective Boot: A heavy-duty poly-vinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity in harsh environments.

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 preferred setting: 1 for the softest ride and 9 for maximum firmness.

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically valved and sized to function correctly on vehicles that have already been equipped with a 5-inch to 6-inch suspension lift kit.

What is the benefit of the larger shock body?
The 2.75-inch body holds more oil than standard shocks, which helps dissipate heat more efficiently, preventing the oil from foaming and maintaining consistent damping performance during long trips.
