Summary: The Rancho RS9000XL series provides industry-leading adjustability for classic Ford trucks, featuring a 9-position manual tuning knob that allows drivers to customize damping levels on the fly. This Tier 2 adjustable shock is designed to solve the conflict between daily street comfort and heavy-duty utility, offering a firm setting for towing and a softer profile for unladen cruising. Engineered for 0″ of rear lift, these shocks maintain the factory ride height while significantly upgrading the vehicle’s damping control and heat dissipation capabilities.

• Large Diameter Shock Body: A 2.75-inch heavy-duty body provides increased fluid capacity to ensure cooler operation and reduced fade during strenuous use.
• Nitrogen Gas Pressurized: High-pressure gas charging provides immediate response to road imperfections to ensure consistent tire-to-road contact.
• Nitro-Carburized Piston Rod: A 18mm hardened piston rod provides superior corrosion resistance and structural integrity to ensure long-term durability in harsh environments.
