Summary: The Rancho RS90000XL 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 ride to a firm setting optimized for towing or heavy hauling. Engineered to accommodate a 1.5-inch lift, this set ensures your Chevy R-20 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 the driver can customize ride stiffness for any load or road condition.
• Nitrogen Gas Charged: High-pressure gas optimization provides a consistent response by minimizing aeration to ensure fade-free performance during spirited driving.
• Large Shock Body: A heavy-duty 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty use.

Frequently Asked Questions
