Part Number: RS994287

Summary: The Rancho RS9000XL series provides industry-leading versatility for high-clearance Ford F-150 applications. Featuring a 9-position manual adjustment knob, these shocks allow drivers to instantly tune damping levels to compensate for varying payloads or terrain. Whether you are daily driving, towing a heavy trailer, or navigating off-road trails, this Tier 2 adjustable system solves the compromise between street comfort and controlled performance.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the perfect ride for towing, hauling, or off-roading.
• Nitrogen Gas Charging: Pressurized gas provides a reduction in aeration and foaming to ensure consistent performance during aggressive cycling.
• Heavy-Duty Body: A 2.75-inch diameter shock body provides increased fluid capacity to ensure lower operating temperatures during heavy-duty use.
• Polyurethane Bushings: High-durometer polyurethane provides enhanced durability and reduced deflection to ensure precise axle control.
