Why these springs
The rear springs on a heavy-duty truck are built for maximum load, which makes an empty truck ride harsh. Carli's rear leaf springs for 2019–2025 Ram 3500 4x4 diesel change how the rear rides and sits, with 1″ of lift, and work with Carli's rear shocks and systems.
Who they're for
A good fit if you want a smoother rear ride or need the rear height to match a Carli front lift. Check the payload, air-ride and system notes below before ordering, since rear springs change how the truck carries weight.

Plan for (sold separately / required)
- The XHD full replacement leaf springs designed for those with constant 2,000lbs in the bed . Designed for the pop-up campers like the four wheel campers hawk. Although, it will work with any 2,000lb. Constant load. This is not a leaf spring pack designed to run unloaded, it requires the 2,000lbs load to sit at the intended height and properly function. Being a far heavier spring rate than our standard leaf spring and designed to operate with a much higher center of gravity, we recommend 2.5″ remote reservoir shocks & custom shock tuning for optimal control and ride quality
