Rancho RS9000XL 0″ Lift Shocks for 2005-2016 Ford F-350 4WD Dual Rear Wheel Chassis

Part Number: RS999042

Summary: The Rancho RS9000XL series provides industry-leading adjustability for Ford F-350 owners who demand versatility from their heavy-duty suspension. Featuring a 9-position manual tuning knob, these shocks allow you to instantly transition from a soft street ride to a firm setting optimized for heavy towing or hauling. Engineered for dual rear wheel chassis applications, this set ensures consistent damping control and heat dissipation under extreme loads.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides 400% change in damping force to ensure the driver can tune for specific towing or payload requirements.
• Large Diameter Shock Body: The 2.75-inch heavy-duty body provides increased fluid capacity to ensure cooler operating temperatures during high-demand hauling.
• Nitrogen Gas Pressurized: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent damping response on uneven terrain.
• Polyurethane Bushings: Performance-grade polyurethane material provides enhanced durability compared to rubber to ensure a longer service life and better road feel.
