Air Spring Kit W/compressor | Wireless Controller | 0-6" Lifts | Toyota Tundra (07-21)

Built for Tundra owners who tow and haul, this rear air spring kit levels your truck under load — keeping your trailer level, reducing tongue weight sway, and protecting your frame from bottoming out. With up to 5,000 lbs of load support and a wireless controller for on-the-fly adjustment, you get the stability that heavy-duty work demands.

Installed and serviced at Road Runner Wheels & Tires. Most air spring kits go in the same day. Call (678) 400-6467 to schedule.

What's included

• Air Spring Kit (0–6" lifts) — Two RC-branded double convoluted airbags with internal bump stops, sized for your Tundra, engineered to support up to 5,000 lbs of load.
• Wireless Air Bag Controller Kit with Compressor — Lets you adjust ride height on demand from inside the cab; includes DOT-approved air lines and 1/4" push-connect fittings for fast, tool-free connections.

Important notes

• Minor drilling required during installation.
• This kit does not increase your truck's towing capacity — it levels the truck under load and reduces sway and bottoming-out, but does not raise payload or towing limits.
