Rancho RS9000XL 2.5-4″ Front Lift Shocks for 1969-1991 GMC Jimmy 4WD

Part Number: RS999001

Summary: The Rancho RS9000XL series delivers industry-leading flexibility for classic GMC Jimmy owners who transition between daily driving, towing, and off-road use. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow you to instantly tune your damping profile to match specific terrain or load requirements. Engineered to accommodate 2.5 to 4 inches of lift, they provide the necessary travel and control to maintain stability in lifted 4WD applications.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping control to ensure the perfect balance between street comfort and off-road firmness.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operation and reduced fade during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas optimization provides a faster response rate to ensure consistent tire-to-road contact on uneven surfaces.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against trail debris.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
These shocks feature an external 9-position knob located at the base of the shock body. Simply turn the dial to your desired setting: 1 for the softest ride and 9 for maximum firmness.

Will these shocks lift my GMC Jimmy?
No, these shocks do not create lift. They are specifically engineered with the correct extended and compressed lengths to function on vehicles already equipped with a 2.5 to 4-inch suspension lift.

What is the benefit of the large 2.75-inch body?
The larger body houses more fluid than standard shocks, which allows for better heat dissipation. This prevents the oil from foaming (aeration), ensuring your damping remains consistent even during spirited off-road driving.
