Rancho RS9000XL 2.5″ Rear Lift Shocks for 2005-2010 Ford F-350 4WD Dual Rear Wheel

Part Number: RS999254

Summary: The Rancho RS9000XL series delivers industry-leading versatility for heavy-duty applications, specifically engineered for the Ford F-350 Super Duty. Featuring a 9-position manual adjustment knob, these shocks allow owners to instantly tune damping levels to compensate for varying payloads or towing requirements. This Tier 2 adjustable system solves the “one size fits all” damping compromise, providing a firm ride for stability under load and a softer setting for unladen street comfort.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure precise ride control across towing, hauling, and off-road environments.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas displacement provides immediate response to road irregularities to ensure consistent tire-to-surface contact.
• 18mm Nitro-Carburized Rod: A heavy-duty hardened piston rod provides superior scuff resistance to ensure long-term seal integrity in harsh environments.

Frequently Asked Questions

How do I adjust the settings on these shocks?
The RS9000XL features a manual knob located at the base of the shock; simply turn the dial to your desired firmness level (1 for softest, 9 for firmest).

Will these shocks lift my Ford F-350?
No, these shocks do not create lift. They are specifically valved and length-tuned to accommodate Ford F-350 models already equipped with approximately 2.5 inches of rear lift.

Are these compatible with Chassis Cab models?
No, these shocks are designed for the standard pickup bed configurations and exclude Chassis Cab models due to different rear suspension geometry.
