Ram 3500 Air Suspension Kit - Rear - Firestone - Ride-Rite All-In-One Kit - `13-`25. The Ride-Rite All-In-One rear air helper kit for 2013–2025 RAM 3500 4WD is built to level loads and return the truck to its designed ride height when hauling or towing. This complete kit ships with air helper springs, an onboard analog compressor and all required hardware for a consolidated installation.

This system reduces rear squat under load and restores proper stance without complex modifications. The kit includes a standard-duty compressor with a no-drill mounting plate for faster installation, an analog backlit gauge that mounts inside the vehicle, and Ride-Rite air springs sized for heavy-duty use. Designed to work with most factory mounting points and compatible with in-bed hitches, the kit supports up to 5,000 lbs of load-leveling capacity (do not exceed GVWR). Typical install time is 1–2 hours with the included step-by-step manual.
