Part Number: RS999120

Summary: The Rancho RS90000XL series provides industry-leading versatility for owners of the GMC G-1500 and Jeep Wagoneer. Featuring a 9-position manual adjustment knob, these shocks allow you to instantly tune your damping profile from soft to firm to accommodate varying loads or terrain. Specifically configured for 1.5-inch front lift heights, they provide the necessary travel and control to maintain ride quality on leveled or mildly lifted vintage platforms.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping control to ensure the perfect balance between street comfort and heavy-duty towing stability.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent performance during rapid suspension cycling.
• Heavy-Duty Body: A large-diameter shock body provides increased fluid capacity to ensure lower operating temperatures during extended use.
• OE-Style Mounts: Application-specific mounting hardware provides a direct-fit installation to ensure a secure connection to the factory chassis points.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS90000XL features a manual knob located at the base of the shock; simply turn the dial to your desired setting (1 for softest, 9 for firmest).

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically configured with the correct travel lengths for vehicles already equipped with a 1.5-inch front lift.

What is the benefit of the larger shock body?
The increased oil capacity allows the shock to dissipate heat more effectively, which prevents damping fade during repetitive use on rough roads.
