Summary: The Rancho RS9000XL series provides industry-leading adjustability for drivers who demand total control over their ride quality. Featuring a 9-position manual tuning knob, these shocks allow you to instantly transition from a soft street feel to a firm setting optimized for towing or heavy hauling. Specifically configured for a 1.5-inch lift, this set ensures your GMC G-1500 maintains proper suspension travel and damping performance across varied terrains.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure custom-tailored ride control for any load or road condition.
• Large Shock Body: A heavy-duty 2.75-in. diameter body provides increased fluid capacity to ensure cooler operation and consistent performance during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas optimization provides a reduction in aeration and foaming to ensure immediate response and fade-free damping.
• Nitro-Carburized Rod: A specialized 18mm piston rod coating provides superior corrosion resistance to ensure long-term durability in harsh environments.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
These shocks feature a manual 9-position knob located at the base of the shock body, allowing you to click through settings without tools.

Will these shocks lift my GMC G-1500?
No, these shocks do not create lift. They are specifically valved and lengthened to work with a vehicle that already has a 1.5-inch lift kit installed.

Are these shocks suitable for towing?
Yes, the higher settings (7-9) are specifically engineered to provide the extra damping required to control trailer sway and heavy rear-end loads.
