This Firestone 2706 Ride-Rite RED Label Extreme Duty air spring kit is a heavy-duty rear helper spring system designed to install between the frame and rear suspension of pickup trucks. It’s intended for 2014-2025 RAM 2500 2WD/4WD models and engineered to support demanding loads for towing, hauling, or stabilizing the truck under cargo.
Constructed with commercial-grade rubber bellows featuring four reinforced layers, this kit incorporates high alloy steel brackets and Grade 8 fasteners throughout. The air springs are rated up to 150 PSI operating pressure, and all components carry Firestone’s signature coating for corrosion resistance. The design allows for a mostly no-drill installation on compatible vehicles, includes all required hardware, fittings, and valves for manual fill, and features air springs without internal jounce bumpers.
When properly installed, this kit levels the rear under heavy loads, reduces sag, improves towing stability, and enhances ride comfort. It helps maintain manufacturer ride height, improves braking performance and handling when carrying gear such as slide-in campers, trailers, or boats. This setup is ideal for those who require superior load carrying capability without exceeding their vehicle’s GVWR, and want reliable, long lasting durability for tough service.
