Part Number: RS999244 / RS999227

Summary: The Rancho RS9000XL series provides the ultimate in ride control versatility for your GMC K2500. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow you to instantly transition between a soft street ride and firm damping for heavy towing or off-road excursions. Specifically configured for vehicles with a 4-inch lift, this set ensures your suspension maintains optimal travel and control regardless of the terrain or load.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure custom-tailored ride control for street, trail, or towing.
• Large Shock Body: A massive 2.75-in. diameter reserve tube provides increased oil capacity to ensure cooler operation and consistent performance during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas charging provides a reduction in aeration and foaming to ensure immediate response and fade-free damping.
• Polyurethane Bushings: High-durability polyurethane material provides reduced deflection to ensure improved steering response and long-term reliability.
