Carli 1" Lift Full Progressive Leaf Spring Pack 13-18 Ram 3500 With Auto Level Air Suspension

Upgrade your Ram’s factory air-assist rear suspension with a setup that rides smoother, works smarter, and keeps your truck fully capable, even if the air system ever fails.

This Carli Full Progressive Leaf Spring Kit replaces the stiff factory rear leaf's with a true progressive spring pack, giving your 3500 a 1"– 2" lift and a massive improvement in unloaded ride quality. The springs carry the truck at the new ride height, while the factory air bags only assist when needed, meaning more up-travel, less harsh air-spring “ramp,” and a smoother ride everywhere.

To make it all work seamlessly, the kit includes bag spacers, sensor relocation brackets, hardware, and a custom air-tank relocation to clear Carli radius arm drop brackets. Everything is engineered so the truck keeps its factory payload rating and the auto-level system continues functioning properly.

If the air system ever fails?
No worries, the progressive leaf's can support the load by themselves, letting you finish the job or get home safely.

Notes:
• The “ALT Trailer Height” drop-down feature won’t function when unloaded (the springs now carry the static ride height), but works normally under load.
• Fits only Ram 3500 4x4 trucks equipped with the factory Auto-Level Air Assist (ALAS) rear suspension.
