Summary: The Rancho RS90000XL series delivers industry-leading versatility for heavy-duty applications. Featuring a 9-position manual tuning knob, these shocks allow owners of Chevy R30 and R3500 trucks to instantly adjust damping levels to match changing loads or road conditions. Whether the vehicle is unladen for street cruising or fully loaded for towing, this adjustable technology provides the perfect balance of stability and comfort for the rear suspension.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the ideal ride quality for both empty beds and heavy towing.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
