Summary: The Rancho RS9000XL series delivers industry-leading versatility for the GMC K2500, featuring a globally recognized 9-position manual adjustment knob. This Tier 2 adjustable system allows owners to instantly transition from a plush street ride to a firm setting optimized for heavy towing or off-road stability. Engineered with a massive shock body for increased oil capacity, these shocks solve the compromise between daily comfort and heavy-duty performance.

Features

• 9-Position Tuning: A manual adjustment knob provides 400% change in damping force to ensure precise control across various towing and terrain conditions.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitro-Gas Charging: High-pressure nitrogen gas provides a barrier between oil and air to ensure consistent performance by preventing aeration and fade.
