Summary: The Rancho RS9000XL series provides unparalleled control for your GMC Sierra 2500HD by featuring a globally recognized 9-position manual adjustment knob. This Tier 2 adjustable system allows you to instantly tune your damping profile from a soft street ride to a firm setting optimized for heavy towing or hauling. Engineered to eliminate the compromise between comfort and capability, these shocks ensure your heavy-duty truck remains composed under varying load demands.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine distinct levels of damping force to ensure the perfect ride quality for any terrain or payload.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas optimization provides a reduction in aeration and foaming to ensure consistent damping response.
• Fluon-Banded Piston: A specialized piston coating provides a consistent seal between the piston and pressure tube to ensure long-term durability and smooth travel.
