Part Number: RS999055

Summary: The Rancho RS90000XL series provides industry-leading versatility for heavy-duty applications through its globally recognized adjustable damping technology. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly transition from a soft street ride to a firm setting optimized for towing or aggressive off-road use. Engineered for vehicles with 5-6 inches of front lift, this nitrogen-gas pressurized shock delivers consistent performance by reducing aeration and fade under high-stress conditions.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the vehicle is perfectly calibrated for specific payloads or terrain.
• Nitrogen Gas Charging: Pressurized gas stabilization provides a reduction in oil foaming and aeration to ensure consistent damping control during rapid suspension cycling.
• Large Shock Body: A heavy-duty 2.75-inch diameter body provides increased fluid capacity to ensure lower operating temperatures during demanding use.
• Polyurethane Bushings: High-density polyurethane material provides enhanced durability and pivot resistance to ensure long-term service life in harsh environments.

Frequently Asked Questions

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

Will these shocks provide my truck with a 6-inch lift?
No, these shocks do not create lift. They are specifically valved and length-matched for vehicles that already have a 5 to 6-inch suspension lift kit installed.

What is the benefit of the nitrogen gas charge?
Nitrogen gas prevents the shock oil from foaming (aeration) during high-speed movement, which ensures your damping stays consistent even on rough washboard roads.
