Part Number: RS999056

Summary: The Rancho RS90000XL series delivers industry-leading versatility for heavy-duty applications. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly adjust damping levels to compensate for varying payloads or terrain. Whether you are towing a heavy trailer or driving unloaded on the highway, this adjustable system provides the specific firmness required to maintain control and comfort.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the perfect ride quality for towing, hauling, or off-road use.
• Large Shock Body: The 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty cycles.
• Nitrogen Gas Charged: High-pressure gas charging minimizes air-to-oil mixture (foaming) to ensure consistent damping performance under load.
• Protective Boot: A heavy-duty polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.
