Product Description

The Firestone 2478 Ride-Rite Rear Air Helper Spring Kit is engineered to provide adjustable rear suspension support for 2007-2025 Dodge Ram 3500 trucks with either 2WD or 4WD on Cab & Chassis variants. Installed between the frame and the rear suspension, this kit uses high-quality convoluted air springs to help level your truck when hauling or towing heavy loads, improving ride quality, stability, and braking effectiveness under load.

With an adjustable air pressure range from approximately 5-100 PSI and individual inflation valves, drivers can fine-tune air spring support for varying payloads or uneven loads. The kit includes all necessary components such as mounting brackets, air line, inflation valves, and hardware for a complete installation, which typically takes about 1-2 hours with basic tools. Designed for durability and performance, the 2478 kit helps reduce suspension fatigue, maintain proper level ride height, and enhance handling confidence when carrying heavy cargo or towing trailers.
