Rancho RS9000XL 2.5-4″ Rear Lift Shocks for 1992-2000 GMC Yukon 4WD Old Body

Part Number: RS999190

Summary: The Rancho RS9000XL series delivers industry-leading versatility for the 1992-2000 GMC Yukon 4WD. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow owners to instantly transition between a soft street ride and a firm setting for heavy towing or off-road excursions. Engineered to accommodate 2.5 to 4 inches of rear lift, they provide the necessary travel and damping control to manage the increased center of gravity on lifted Old Body Style (OBS) Yukons.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect ride quality for any terrain or load requirement.
• Nitrogen Gas Charged: High-pressure gas optimization provides a consistent response by reducing aeration to ensure fade-free performance during spirited driving.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty use.
• Heavy-Duty Piston: A 1.25-inch sintered iron piston provides structural integrity and precision valving to ensure long-term durability on lifted applications.

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 body; simply turn the dial to your preferred setting—1 for softest, 9 for firmest.

Will these shocks lift my GMC Yukon?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to safely accommodate a Yukon already equipped with a 2.5″ to 4″ suspension lift.

Do these include the protective boots?
Yes, these shocks come standard with Rancho’s signature red protective boots to shield the piston rod from debris and contaminants.
