Summary: The Rancho RS9000XL series delivers industry-leading versatility for the GMC R3500 through its globally recognized adjustable damping technology. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly transition from a soft street ride to a firm setting optimized for heavy towing or hauling. Engineered to maintain factory ride height, this set provides a custom-tuned suspension feel without the need for permanent vehicle modifications.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides 400% change in damping force to ensure total control over ride quality and firmness.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty cycles.
• Nitrogen Gas Charged: High-pressure gas optimization provides a barrier between oil and air to ensure consistent performance by preventing aeration.
• Fluon-Banded Piston: A specialized piston coating provides a consistent seal between the piston and pressure tube to ensure rapid response to road irregularities.
