Summary: The Rancho RS9000XL series provides industry-leading adjustability for the GMC K1500 and Yukon platform. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly transition from a soft street ride to a firm setting optimized for towing or heavy off-road use. This complete set is specifically configured for vehicles equipped with a 2.5 to 4-inch lift, ensuring proper suspension travel and damping control across all four corners.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the driver can customize ride quality for specific payloads or terrain.
• Large Shock Body: The 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas optimization provides a faster response rate to ensure consistent contact between the tire and the road surface.
• Heavy-Duty Rod: An 18mm nitro-carburized piston rod provides superior structural rigidity to ensure long-term durability in harsh environments.
