Arnott BAG-RA150313 Rear Air Helper Spring Kit

Arnott BAG-RA150313 is a rear air suspension helper spring kit for Ram and Dodge Ram trucks that need added load support for towing, hauling, and weight transfer control. It uses adjustable air pressure to help maintain ride height, steering response, and braking stability under changing cargo conditions.

Key Features

  • Rear air helper spring kit for load-leveling support
  • Adjustable air pressure for different load demands
  • Rubber bellows construction with black bellows finish
  • Mounting hardware included for installation
  • 16 mounting studs for secure attachment
  • Reduces axle-to-frame contact to help limit bottoming out
  • Helps reduce inner-leaf friction for smoother suspension movement

Detailed Description

This Arnott air suspension helper spring kit is built to add support at the rear suspension on Ram 2500, Ram 3500, and Ram 1500 applications listed below. By adding air pressure as load changes, BAG-RA150313 helps keep the truck more level while supporting steering control and braking effectiveness during weight shift events. The rubber bellows design is paired with included mounting hardware for a direct service replacement approach on the specified rear applications.

Compatible With 2011-2013 Ram 2500 rear, in-bed hitch compatible; 2011-2012 Ram 3500 rear, in-bed hitch compatible; 2003-2010 Dodge Ram 2500 rear, in-bed hitch compatible; 2003-2010 Dodge Ram 3500 rear, in-bed hitch compatible; and 2006-2008 Dodge Ram 1500 rear, in-bed hitch compatible. This part number, BAG-RA150313, is a practical choice when the rear suspension needs additional support for towing or payload management on Ram and Dodge Ram trucks.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Uses

  • Rear sag under towing or heavy cargo
  • Excessive suspension compression during load changes
  • Reduced steering stability when the truck is carrying weight
  • Braking imbalance caused by rear-end squat
  • Frequent bottoming out over bumps or uneven roads

Installation Notes and Tips

Install BAG-RA150313 at the rear suspension only on the listed Ram and Dodge Ram applications. Verify in-bed hitch clearance before installation, since the fitment notes specify hitch compatibility. Check air pressure settings after installation and adjust them based on load conditions to maintain proper ride height and handling balance.

Quality Assurance

Arnott manufactures suspension components for vehicle-specific applications, and this helper spring kit uses rubber bellows construction with included mounting hardware for service replacement on the listed trucks. Confirm fitment by year, make, model, and rear position before ordering.
