Summary: The Rancho RS9000XL series provides industry-leading versatility for heavy-duty applications. Featuring a 9-position manual adjustment knob, these shocks allow you to instantly tune your damping profile to compensate for varying payloads or off-road conditions. Engineered for the Chevy K2500 and GMC Yukon, this system delivers a custom-tailored ride that transitions seamlessly from comfortable highway cruising to firm, controlled towing performance.

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 control.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during sustained cycling.
• Nitrogen Gas Charged: High-pressure gas integration provides a reduction in aeration and foaming to ensure consistent damping performance in demanding environments.
