Rancho RS9000XL 0″ Lift Shocks for 1999-2004 Ford F-450 / F-550

Part Number: RS999267 / RS999126

Summary: The Rancho RS9000XL series provides unparalleled control for heavy-duty Ford trucks by featuring a specialized 9-position manual tuning knob. This Tier 2 adjustable technology allows owners to instantly transition from a soft street ride to a firm setting required for heavy towing or hauling. Designed for stock height applications, these shocks solve the common issue of “one size fits all” valving by putting damping control directly in the hands of the driver.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the perfect ride quality for varying load weights.
• Large Shock Body: A massive 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas displacement provides immediate response and prevents cavitation to ensure consistent performance on rough terrain.
• Polyurethane Bushings: High-durability polyurethane material provides a secure mounting interface to ensure reduced vibration and long-term service life.
