Part Number: RS999059 / RS999060

Summary: The Rancho RS9000XL series provides the ultimate in damping flexibility for lifted K-Series trucks and SUVs. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow owners to instantly tune the ride quality to compensate for varying payloads, towing demands, or off-road conditions. Engineered for vehicles with 5 to 6 inches of suspension lift, this set delivers a custom-tailored driving experience that transitions seamlessly from soft street comfort to firm, controlled performance.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure precise control over ride firmness and stability.
• Large 2.75-in. Body: A heavy-duty 70mm body diameter provides increased fluid capacity to ensure cooler operation during heavy-duty hauling or off-road use.
• Nitrogen Gas Pressurized: High-pressure gas charge minimizes air-to-oil mixture (aeration) to ensure consistent damping response and fade resistance.
• Fluon-Banded Piston: A specialized piston coating provides a consistent seal between the piston and pressure tube to ensure maximum durability and smooth travel.
