Product Description

The Firestone 2404 Ride-Rite Rear Air Helper Spring Kit is engineered for heavy-duty cab-chassis trucks - Ford F-550 (1999-2008) and Dodge/Ram 4500/5500 (2007-2024). Designed to support up to 5,000 lb of additional load, this kit maintains optimal ride height, reduces leaf-spring fatigue, and improves vehicle stability under heavy towing and hauling conditions.

Installation is straightforward: drill and bolt the dual air springs between the frame and suspension in about 1-2 hours, ensuring at least 9.5" tire-to-frame and 2" above frame clearance. With adjustable air pressure ranging from 5-100 PSI and individual inflation valves for precise leveling, this kit enhances braking, steering, and ride comfort. Proudly manufactured in the USA and backed by a limited lifetime warranty, the 2404 kit includes all brackets, air lines, valves, hardware, and instructions needed for a complete setup.
