Toyota Tundra Air Suspension Kit - Rear - Firestone - Ride-Rite All-In-One Wireless - 07-21 is a complete rear air helper spring and compressor package designed for Tundra owners who tow or haul. This All-In-One kit supplies the parts needed to reduce squat and return the truck to its intended ride height when loaded.

The Ride-Rite All-In-One Wireless kit pairs Firestone air helper springs with an onboard compressor, ECU and wireless app control for simple load-leveling and monitoring. The kit is engineered to work with 2WD and 4WD models from 2007–2021 and is rated for up to 5,000 lbs of load-leveling capacity (do not exceed vehicle GVWR). Firestone’s updated AIO design includes a no-drill mounting plate for the compressor and ECU to simplify installation, and most applications use existing factory holes for the air springs. The wireless controls use Bluetooth app pairing (Android and iPhone) with two memory presets and live system feedback; the system maintains a minimum of 5 PSI when not in use.
