Summary: The Rancho RS9000XL series delivers industry-leading versatility for heavy-duty applications. Featuring a 9-position manual tuning knob, these shocks allow owners to instantly adjust damping levels to compensate for varying payload weights or towing requirements. This Tier 2 adjustable technology provides a custom-tailored ride, transitioning from a comfortable street feel to firm, controlled damping for maximum stability under load.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect ride for towing, hauling, or daily driving.
• Large Shock Body: A heavy-duty 2.75-inch diameter body provides increased fluid capacity to ensure consistent performance and reduced fade during high-stress operation.
• Nitrogen Gas Charged: High-pressure gas charging provides immediate response and prevents aeration to ensure optimal tire-to-road contact.
• Protective Boot: A durable poly-vinyl accordion boot protects the piston rod from debris to ensure long-term seal integrity.
