Rancho RS9000XL 2.5-4″ Front Lift Shocks for 1988-1999 GMC K1500 4WD

Part Number: RS999001

Summary: The Rancho RS9000XL series delivers industry-leading versatility for your GMC K1500 or Yukon. Featuring a 9-position manual tuning knob, these shocks allow you to instantly adjust your compression damping to transition from smooth street cruising to firm control for towing or off-road use. Configured for 2.5-4 inches of front lift, they provide the necessary travel and damping force required for leveled or lifted applications.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping control to ensure the perfect ride quality for any terrain or load requirement.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas charge provides a consistent response by minimizing aeration to ensure fade-free performance.
• Protective Boot: A heavy-duty poly-vinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity.

Frequently Asked Questions

How do I adjust the stiffness of these shocks?
The RS9000XL features a manual 9-position knob located at the base of the shock body. Simply turn the dial to your desired setting; lower numbers for a softer ride and higher numbers for increased firmness.

Will these shocks lift my GMC K1500?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to work with vehicles already equipped with a 2.5 to 4-inch lift kit.

Do these shocks come with boots?
Yes, these shocks include red poly-vinyl boots to protect the piston rod and oil seal from road debris and off-road contaminants.
