Part Number: RS999265

Summary: The Rancho RS9000XL series provides the ultimate in ride control versatility for your GMC Sierra 1500 4WD. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow you to instantly tune your damping profile from soft to firm. Whether you are daily driving, towing heavy loads, or navigating off-road terrain, this set provides a custom-tailored suspension response to eliminate sway and improve stability.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the driver can optimize ride quality for street, towing, or off-road use.
• Large Shock Body: A massive 2.75-in. diameter body provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty cycles.
• Nitrogen Gas Charged: High-pressure gas integration provides immediate response to road irregularities to ensure consistent tire-to-ground contact.
• Polyurethane Bushings: High-performance polyurethane material provides enhanced durability compared to rubber to ensure long-term pivot point integrity.

Frequently Asked Questions

How do I adjust the firmness of these shocks?

Will these shocks lift my GMC Sierra?
No, these shocks are configured for a 0-inch lift height and are designed to replace your factory-length shocks while maintaining stock ride height.

Do I need special tools for the adjustment?
No special tools are required; the external adjustment knob is designed to be turned by hand, allowing for quick changes at the job site or trailhead.
