This is the Firestone Ride-Rite 2525 Rear Air Helper Spring Kit, designed to help level and support your 2009-2014 Ford F-150 2WD or 4WD (excluding Raptor and FX2). It installs between your truck’s frame and rear suspension to adjust air pressure according to changing loads, maintaining a proper stance.
Built with rugged convoluted rubber air springs, this complete kit includes upper & lower brackets, air line, separate inflation valves, and all necessary hardware. The system operates across a wide pressure range of 5-100 PSI for maximum flexibility and load support.
With this kit you’ll experience increased load-carrying capacity (up to 5,000 lbs per set), improved stability and brake effectiveness, reduced suspension sag and inter-leaf friction, and lessBODY bottoming out. Perfect for towing, hauling, or daily driving with shift-in-weight issues.
