Summary: The Rancho RS9000XL series delivers industry-leading versatility for heavy-duty vans and utility vehicles. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow drivers to instantly tune damping levels to compensate for varying payload weights or towing requirements. Whether configured for a smooth highway commute or firm stability under load, these shocks provide the precise control necessary for the Dodge B-Series and AM General platforms.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the perfect balance between street comfort and heavy-duty towing stability.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent performance during sustained cycling.
• Heavy-Duty Body: A large 2.75-inch diameter reserve tube provides increased oil capacity to ensure lower operating temperatures during demanding use.
• Protective Boot: A durable polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.
