The Carli Progressive Leaf Springs with 2″ Rear Lift is a premium rear suspension upgrade designed for 2019 and newer Dodge Ram 3500 4×4 diesel trucks equipped with factory auto‑leveling air suspension. This full progressive leaf spring pack converts the rear suspension to a progressive design that improves unloaded ride quality while maintaining the truck’s factory payload and auto‑leveling function — delivering both comfort and performance.

Featuring a 1″–2″ rear lift that matches Carli’s front lift systems, these leaf springs help balance the truck stance, maintain proper suspension geometry, and reduce issues like axle wrap and wheel hop seen with stock springs. The kit includes sensor, airbag, and airtank relocation hardware, airline, and fittings for a complete installation without sacrificing air‑assist functionality.
