Rancho RS9000XL 4″ Rear Lift Shocks for 2009-2013 Ford F-150 4WD

Part Number: RS994287

Summary: The Rancho RS9000XL series provides industry-leading versatility for the Ford F-150 and Lincoln Mark LT. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly adjust damping levels to compensate for varying payloads or off-road conditions. Designed specifically for vehicles configured with a 4-inch rear lift, they deliver a custom-tailored ride that transitions seamlessly from highway comfort to firm, controlled towing performance.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the vehicle is perfectly calibrated for street, trail, or heavy hauling.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitro-Carburized Rod: The heavy-duty piston rod provides increased scuff resistance and corrosion protection to ensure long-term seal integrity.
• Polyurethane Bushings: High-performance bushings provide enhanced durability and reduced deflection to ensure precise suspension geometry.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
These shocks feature an external 9-position knob at the base of the shock body that can be turned by hand to increase or decrease damping resistance.

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically lengthened and configured for vehicles that already have a 4-inch rear lift installed.

Are these shocks nitrogen charged?
Yes, they are gas-pressurized to minimize air-to-oil mixture (aeration), ensuring consistent damping performance under load.
