Firestone Ride-Rite Air Helper Spring Kit Rear 1992+ Ford E350 Cutaway (W217602061)

If you're driving a 1999-2024 Ford E-350 Super Duty, especially one that carries heavy loads or is used as a cutaway for RV conversions, you know how much the suspension can sag. This Firestone Ride-Rite Air Helper Spring kit is designed to give your rear suspension a boost, helping to keep your vehicle level and stable even when you're pushing its limits. These springs work by using adjustable air pressure to supplement your existing leaf springs, effectively increasing your vehicle's safe load-carrying capacity and improving overall ride quality.

What makes these kits so popular is their ability to adapt to changing conditions. You can adjust the air pressure on each side independently, which is a big help when you have an off-center load. This feature helps keep your E-350 level, reducing sway and making it easier to handle. The system also works to reduce suspension fatigue by taking some of the strain off your factory springs and helps prevent bottoming out on rough roads. Firestone designed these kits to be a no-drill installation for most applications, meaning they typically use the factory mounting holes on your E-350's frame, making the installation process more straightforward.

This kit includes everything you need to get your air helper springs installed: the air helper springs themselves, all the necessary brackets, airlines, and inflation valves. Firestone backs this popular kit with a two-year limited warranty, giving you peace of mind. While this kit is specifically for the E-350 Super Duty, Firestone offers similar Ride-Rite kits for a wide range of trucks and vans, so you can find a solution for many different vehicles.
