Keep Your Truck Level No Matter the Load

When your Ford Super Duty is packed with gear, towing a trailer, or just carrying the weight of the job, the last thing you want is a sagging rear end and sketchy handling. That’s exactly where the Firestone 2550 Ride-Rite Air Spring Kit comes in. It gives you the power to level out your truck even under heavy loads, making every drive smoother, safer, and a lot less stressful. By adjusting the air pressure, you can fine-tune your ride whether you're running empty or maxed out with a fifth-wheel. Better stability means better braking, sharper steering, and a whole lot less white-knuckle driving when the road gets rough. And because this kit installs with minimal hassle, you won’t spend your whole weekend in the garage. Whether you're hauling heavy equipment, towing the family RV, or just loading up for work, Ride-Rite helps your truck drive like it’s meant to—strong, stable, and ready for anything.

Heavy Duty Air Support Designed for Real Work

The Firestone 2550 Rear Ride-Rite Air Spring Kit is precision-engineered for 1999-2004 & 2008-2010 Ford F-250 and F-350 models, supporting both 2WD and 4WD configurations. Designed with heavy-duty double-convoluted air springs, this system provides up to 5,000 pounds of load-leveling support, dramatically improving ride quality and load management. Each air spring adjusts from 5 to 100 PSI, letting you easily adapt to changing payloads or towing setups without sacrificing control. The kit uses high-strength steel brackets and mounts directly to factory locations, meaning no major modifications are required for most stock-height trucks. It’s also fully compatible with in-bed towing setups like gooseneck and fifth-wheel hitches, giving you maximum flexibility for work or play. Firestone’s proven commercial-grade durability ensures the air springs can handle harsh conditions, rough roads, and years of heavy use without missing a beat. Whether you need better towing control, improved rear-end support, or simply a better ride, this kit brings serious capability to your Super Duty.
