Product Description

The Firestone 2603 Ride-Rite Rear Air Helper Spring Kit is engineered for **2015-2022 Ford Transit-350 vans** equipped with **dual rear wheels (DRW) or Transit-350 HD configurations**. This kit installs between the vehicle's frame and rear suspension leaf springs to provide **adjustable pneumatic support** when hauling heavy cargo or towing, helping to keep the vehicle level and stable under load. The double-convoluted air springs allow you to fine-tune air pressure (typically from about 5 to 100 PSI) according to load demands, enhancing ride quality, steering control, and braking effectiveness.

The kit includes everything needed for installation - air springs, heavy-duty brackets, air line tubing, inflation valves, and all mounting hardware, and it typically installs in about 1-2 hours with basic tools. Individual inflation valves allow side-to-side adjustments, which help maintain a level stance even with uneven loads. Designed for durability and reliable performance, the 2603 Ride-Rite helper spring kit is ideal for Transit-350 owners who frequently carry heavy payloads, tow trailers, or need improved rear suspension support for commercial and motorhome applications.
