Summary: The Rancho RS9000XL series provides industry-leading versatility for your GMC K3500 through its globally recognized adjustable damping technology. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly switch between a soft street ride and a firm setting for heavy towing or off-road stability. Engineered for vehicles at factory ride height, this set delivers a custom-tuned feel that adapts to your specific load requirements and driving environment.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides 400% change in damping force to ensure precise control across various towing and hauling scenarios.
• Nitrogen Gas Pressurized: High-pressure gas charge provides a consistent response by minimizing aeration to ensure fade-free performance during heavy-duty cycles.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures under high-stress conditions.
