Summary: The Rancho RS9000XL series delivers industry-leading versatility for the GMC C1500 and Yukon platform. Featuring a sophisticated 9-position manual tuning knob, these shocks allow drivers to instantly adjust damping profiles to match specific hauling, towing, or street cruising requirements. This complete set provides a custom-tailored ride quality that compensates for varying payloads while maintaining the factory 0-inch ride height.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping control to ensure the perfect balance between comfort and stability across different terrains.
• Large Shock Body: A heavy-duty 2.75-in. diameter body provides increased fluid capacity to ensure cooler operating temperatures during heavy towing or hauling.
• Nitrogen Gas Charged: High-pressure gas displacement provides immediate response to road imperfections to ensure consistent tire-to-road contact.
• Protective Boot: A heavy-duty red polyvinyl bellows provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
Each shock features an external 9-position knob at the base. Turning the knob allows you to manually cycle through different damping levels from soft (1) to firm (9).

Will these shocks lift my GMC C1500?
No, these shocks are configured for 0-inches of lift and are designed to replace the factory-length dampers on stock-height vehicles.

Are these shocks nitrogen-charged?
Yes, the RS9000XL series is nitrogen gas pressurized to minimize aeration and provide a more consistent damping response during rapid cycling.
