Summary: The Rancho RS90000XL series provides industry-leading versatility for classic Jeep and AM General utility vehicles. Featuring a 9-position manual adjustment knob, these shocks allow drivers to instantly tune damping levels to transition from comfortable street cruising to firm control for hauling or off-road use. Engineered to maintain factory ride height, they provide a modern performance upgrade for vintage 4WD applications while ensuring consistent stability under varying load conditions.

Features

• 9-Position Tuning: A manually adjustable damping knob provides nine distinct levels of compression/rebound control to ensure the vehicle is optimized for any terrain or payload.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during sustained use.
• Nitrogen Gas Charged: High-pressure gas integration provides a reduction in aeration and foaming to ensure consistent damping response.
• Heavy-Duty Bushings: Polyurethane bushings provide enhanced durability and reduced deflection to ensure long-term service life in rugged environments.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
These shocks feature a 9-position knob located at the base of the shock body; simply turn the dial to increase or decrease damping resistance.

Will these shocks lift my Jeep?
No, these shocks are configured for 0-inches of lift and are designed to replace factory-length dampers without changing vehicle height.

What is the benefit of the larger shock body?
The 2.75-inch body holds more oil than standard shocks, which helps dissipate heat faster and prevents “shock fade” during heavy use.
