Rancho RS9000XL 2.5-4″ Lift Shocks for 1969-1993 Dodge W300, W350 4WD

Part Number: RS999114

Summary: The Rancho RS9000XL series provides industry-leading adjustability for classic Dodge and Plymouth heavy-duty applications. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly transition from a soft street ride to a firm setting optimized for heavy towing or off-road stability. Engineered for vehicles with 2.5 to 4 inches of lift, this set ensures your vintage 4WD maintains modern damping control regardless of the terrain or cargo load.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping resistance to ensure the perfect ride quality for towing, hauling, or daily driving.
• Large Diameter Body: A 2.75-inch heavy-duty body provides increased fluid capacity to ensure lower operating temperatures and reduced fade during extreme use.
• Nitrogen Gas Charged: High-pressure gas charging provides a consistent response and minimizes aeration to ensure precise valving performance.
• Protective Boot Included: A durable red polyvinyl boot 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 stiffness of these shocks?
The RS9000XL features an external 9-position knob located at the base of the shock body. You can manually turn the dial to setting 1 for the softest ride or setting 9 for maximum firmness.

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically configured for vehicles that have already been equipped with a 2.5 to 4-inch suspension lift kit.

What is the best setting for towing?
For towing or heavy hauling, it is recommended to use a higher setting (typically 7-9) on the rear shocks to increase stability and reduce sway.
