Rancho RS9000XL 0″ Rear Lift Shocks for 1977-1979 Ford F-250 4WD

Part Number: RS999179

Summary: The Rancho RS9000XL series provides industry-leading adjustability for drivers who demand total control over their ride quality. Featuring a 9-position manual tuning knob, these shocks allow you to instantly transition between a soft street ride and a firm setting for heavy towing or off-road stability. Designed specifically for the rear of the 1977-1979 Ford F-250 4WD at stock height, these shocks eliminate the compromise between comfort and performance by putting the damping profile in your hands.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the perfect ride for daily commuting, towing, or hauling.
• Large Shock Body: A massive 2.75-inch diameter body provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas charging provides immediate response to road imperfections to ensure consistent 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 durability against debris.

Frequently Asked Questions

How do I adjust the settings on these shocks?
The RS9000XL features a manual knob located on the shock body that can be turned by hand to any of the nine numbered settings.

Will these shocks lift my Ford F-250?
No, these shocks are configured for a 0-inch lift height and are designed to replace factory-length shocks without changing the vehicle’s stance.

What is the benefit of the larger shock body?
The 2.75-inch body holds more oil than standard shocks, which helps dissipate heat faster and prevents “shock fade” during strenuous driving conditions.
