Rancho RS90000XL 0″ Rear Lift Shocks for 1991-1995 Isuzu Pickup

Part Number: RS999113

Summary: The Rancho RS9000XL series provides industry-leading adjustability for owners of the Isuzu Pickup and AM General FJ-9. Featuring a 9-position manual tuning knob, these shocks allow you to instantly transition from a soft street ride to a firm setting optimized for hauling or towing. Built with a massive shock body for increased fluid capacity, these rear shocks are engineered to maintain consistent damping performance under heavy loads.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping control to ensure the vehicle is perfectly tuned for street, towing, or off-road use.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to reduce fluid aeration and ensure fade-free performance during heavy-duty cycles.
• Nitrogen Gas Pressurized: High-pressure gas charge provides immediate response to road irregularities to ensure improved tire-to-road contact.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.

Frequently Asked Questions

How do I adjust the stiffness of these shocks?
The RS9000XL features a 9-position knob located at the base of the shock body. You can manually turn the dial to setting 1 for the softest ride or setting 9 for maximum firmness.

Do these shocks provide any lift to my Isuzu Pickup?
No, these shocks are configured for vehicles with 0 inches of rear lift and are designed to replace the factory-length units while providing improved damping control.

What is the benefit of the large 2.75-inch body?
The larger body houses more hydraulic fluid, which helps dissipate heat faster than standard shocks, preventing the “vague” feeling that occurs when shocks overheat during hard use.
