Rancho RS9000XL 6″ Rear Lift Shocks for 2010-2013 Ford F-150 4WD

Part Number: RS994287

Summary: The Rancho RS9000XL series provides industry-leading versatility for truck owners who demand manual control over their ride quality. Featuring a 9-position adjustment knob, these shocks allow you to instantly tune your damping profile from soft for daily commuting to firm for heavy towing or off-road excursions. Engineered to accommodate a 6-inch rear lift, these shocks deliver a customized performance solution for the Ford F-150 and Lincoln Mark LT, ensuring the vehicle remains stable and composed under various load conditions.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the driver can optimize ride quality for street, towing, or off-road use.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty cycles.
• Nitrogen Gas Charging: Pressurized nitrogen gas provides resistance against oil foaming and aeration to ensure consistent damping performance in demanding environments.
• Protective Boot: A heavy-duty poly-vinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against debris.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The shocks feature a 9-position manual knob located at the base of the shock body. Simply turn the dial to increase or decrease the damping resistance based on your current driving needs.

Will these shocks lift my truck 6 inches?
No, these shocks do not create lift. They are specifically valved and clearanced in length to function correctly on a vehicle that already has a 6-inch rear lift kit installed.

What is the benefit of the larger 2.75-inch body?
The larger body allows for a greater volume of oil. This helps dissipate heat more effectively, which prevents “shock fade” during prolonged use or when carrying heavy loads.
