Rancho RS9000XL 6″ Rear Lift Shocks for 2015-2016 Ford F-150 4WD

Part Number: RS994287

Summary: The Rancho RS900XL series provides industry-leading versatility for Ford F-150 and Lincoln Mark LT owners who demand control over their ride quality. Featuring a 9-position manual adjustment knob, these shocks allow you to instantly tune your damping profile to compensate for heavy towing, off-road excursions, or daily highway commuting. Engineered specifically for vehicles with a 6-inch rear lift, these shocks solve the problem of “one size fits all” valving by putting the final calibration in the driver’s hands.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect balance between street comfort and off-road firmness.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent performance under high-frequency cycling.
• Heavy-Duty 18mm Nitro-Carburized Rod: A massive 18mm piston rod provides increased structural rigidity and scuff resistance to ensure long-term seal integrity.
• Protective Boot: A red polyvinyl accordion boot provides a physical barrier against road debris and moisture to ensure the longevity of the polished piston rod.

Why Choose This Product?

• Engineering Advantage: Unlike standard replacement shocks, the RS9000XL utilizes a massive 2.75-inch body diameter to house more fluid, reducing internal heat and preventing fade during heavy-duty use.
• Performance Benefit: The ability to switch from a soft setting for unloaded driving to a firm setting for hauling prevents the “wallowing” sensation common in lifted trucks.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
These shocks feature a manual 9-position knob located at the base of the shock body; simply turn the dial to your preferred setting—1 for softest, 9 for firmest.

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically configured for vehicles that already have a 6-inch rear lift kit installed to ensure proper travel and geometry.

What is the benefit of the nitrogen gas charge?
The nitrogen charge keeps the internal oil under pressure, which prevents air bubbles from forming (aeration) during fast movement, maintaining consistent damping force.
