Summary: The Rancho RS9000XL series provides industry-leading damping control for the GMC K2500. Featuring a 9-position manual adjustment knob, these shocks allow drivers to instantly tune their ride quality between soft street cruising and firm heavy-duty towing. Designed to accommodate 2.5 to 4 inches of lift, this set ensures your classic K-Series maintains superior tire-to-road contact and stability regardless of the terrain.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure custom-tailored ride control for various loads and conditions.
• Large 2.75-in. Body: A heavy-duty twin-tube gas-pressurized design provides increased fluid capacity to ensure cooler operation and consistent performance during off-road use.
• Nitrogen Gas Charging: Pressurized nitrogen gas provides a reduction in aeration and foaming to ensure immediate response and fade-free damping.
• Protective Boot: An included red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal durability against debris.
