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

Part Number: RS999001

Summary: The Rancho RS9000XL series provides industry-leading adjustability for GMC Jimmy owners who demand versatility from their suspension. Featuring a globally recognized 9-position manual tuning knob, these shocks allow you to instantly transition from a soft street ride to a firm setting optimized for off-road stability or heavy towing. Engineered for vehicles with 2.5 to 4 inches of lift, this set delivers custom-tuned damping control to handle the unique geometry of a lifted 4WD classic.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure precise control across various terrains and load requirements.
• Large Shock Body: A heavy-duty 2.75-in. diameter body provides increased fluid capacity to ensure cooler operation and reduced fade during aggressive maneuvers.
• Nitrogen Gas Pressurization: High-pressure gas charge minimizes air-to-oil mixture to ensure rapid response and consistent damping performance.
• Fluon-Banded Piston: A specialized piston coating provides a consistent seal between the piston and pressure tube to ensure long-term durability and smooth stroke transition.
