Rancho RS9000XL 4″ Rear Lift Shocks for 1980-1996 Ford F-100/F-150 4WD

Part Number: RS999112

Summary: The Rancho RS9000XL series provides industry-leading versatility for Ford F-Series owners who demand control over their ride quality. Featuring a 9-position manual adjustment knob, these shocks allow you to instantly transition from a soft street feel to a firm setting for heavy towing or aggressive off-road use. Engineered to accommodate 4 inches of rear lift, these shocks solve the problem of “one-size-fits-all” valving by putting damping control directly in the driver’s 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 off-roading.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure consistent performance and reduced fade under high-heat conditions.
• Nitrogen Gas Charged: High-pressure gas optimization provides immediate response to road imperfections to ensure maximum tire-to-ground contact.
• Protective Boot: A durable liquid metallic finish and included dust boot provide protection for the piston rod and oil seal to ensure long-term reliability in harsh environments.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features an easy-to-access 9-position knob at the base of the shock body. Simply turn the dial to your preferred setting—lower numbers for a softer ride and higher numbers for firmer damping.

Will these shocks lift my Ford F-150?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to work with a vehicle that already has a 4-inch rear lift kit installed.

Are these shocks sold as a pair?
Yes, this SKU (2xRS999112) includes a pair of two shocks for the rear of your vehicle.
