Product Overview

 

The ReadyLIFT 3" Rear Air Spacer Kit is engineered specifically for 2019–2025 Ram 3500 Dually Diesel 4WD trucks equipped with factory rear air suspension. Designed to work alongside ReadyLIFT coil spring lift systems, this spacer kit restores proper rear ride height while maintaining factory air suspension functionality and load-leveling performance.

Built for heavy-duty towing, hauling, and commercial-use applications, the system provides 3 inches of rear air suspension lift to match front suspension lift kits while preserving the operation of the OEM rear air ride system. The spacers install within the factory rear air suspension setup and help maintain proper suspension geometry, ride height, and load support characteristics.

ReadyLIFT designed this kit specifically for diesel-powered Ram 3500 Dually trucks equipped with rear factory air suspension and recommends its use with the ReadyLIFT 3" Coil Spring Lift Kit (Part #49-19332) to achieve proper front-to-rear lift balance. Now Available at LEER!
