MILLISEC Rear Air Helper Spring Kit for 2009–2022 Ram 1500/1500 Classic — 1000 lb Load-Leveling, Adjustable 5–50 PSI

The MILLISEC rear air spring bags suspension kit upgrades Ram 1500 rear support with adjustable air springs that provide up to 1,000 pounds of load-leveling capacity.

Designed as a direct-fit replacement for common OE helper spring assemblies, this kit gives 2009–2022 Ram 1500 and Ram 1500 Classic owners an easy way to regain ride height, stability, and braking performance when carrying heavy or uneven loads. All required brackets, fittings, and hardware are included so the system can be installed without custom fabrication. The air springs are adjustable between roughly 5 and 50 psi to fine-tune rear support for towing, hauling, or everyday driving.

How does this MILLISEC kit improve towing and hauling performance?

Adding air helper springs supports rear axle preload and prevents excessive sag under load, which keeps tow angles and suspension geometry closer to factory specifications. That stability helps preserve handling and braking feel while reducing stress on chassis components.
