Part Number: RS999001
Summary: The Rancho RS9000XL series delivers professional-grade adjustability to the front of your GMC K3500. Featuring a globally recognized 9-position manual tuning knob, these shocks allow you to instantly switch between a soft street ride and firm damping for heavy-duty towing or off-road use. Specifically configured for 4-inch lift heights, they provide the necessary travel and control to maintain stability on 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.
- Nitrogen Gas Charged: High-pressure gas displacement provides reduced aeration and foaming to ensure consistent performance during aggressive driving.
- Large Shock Body: A heavy-duty 2.75-inch diameter body provides increased fluid capacity to ensure cooler operating temperatures during sustained cycling.
- Liquid Metallic Finish: A premium zinc-plated coating provides superior corrosion resistance to ensure long-term durability in harsh environments.

Frequently Asked Questions
How do I adjust the firmness of these shocks?
Simply turn the 9-position knob located at the base of the shock body to your desired setting; position 1 is the softest and position 9 is the firmest.
Will these shocks lift my GMC K3500 by 4 inches?
No, these shocks do not create lift. They are specifically valved and sized to function with a vehicle that already has a 4-inch suspension lift installed.
What is the benefit of the large 2.75-inch body?
The larger body houses more oil, which helps dissipate heat more efficiently than standard shocks, preventing “shock fade” during heavy use.
