Features to know about

Support That Keeps Your Van Steady and Safe

Factory suspension can struggle under real-world loads—if you're delivering cargo, towing a trailer, or building out a full van conversion. Alpha HD air springs add up to 5,000 lbs of rear support, helping keep your Sprinter level and composed when the weight adds up. No more dragging rear ends, sloppy cornering, or headlight glare that blinds oncoming traffic. Just a stronger stance, more predictable handling, and peace of mind behind the wheel.

Tune Your Ride to Match the Mission

A cargo run doesn't ride the same as a weekend trip and your suspension should reflect that. With air pressure adjustability from 5 to 100 psi, you can fine-tune support based on how much gear you're hauling. Drop pressure when you're running light for a smoother ride or pump it up when the van's packed full. Manual inflation keeps it simple, effective, and easy to manage on your own terms.

Durability You Can Count On, Mile After Mile

From long-haul deliveries to off-grid trails, your van sees more than perfect pavement and this system is built for it. One-inch thick, corrosion-resistant end caps and reinforced with 20 internal support wires for maximum strength under load. Heavy-duty roll plates protect the bags from chafing and extend lifespan. Powder-coated steel brackets fight back against rust, road salt, and rough seasons. If it's bitter cold, scorching heat, or mud-slicked trails, this system is made to outlast whatever the road dishes out, mile after mile, load after load.

Installation That Doesn't Derail Your Weekend

This kit is designed with DIY-ers in mind. Precision brackets bolt to existing mounting points with no drilling, and all components come pre-cut and ready to install. Manual inflation valves mount easily to the rear bumper or license plate bracket. No complicated wiring or air tools required. Just a straightforward upgrade you can knock out in a few hours and feel on the very next trip.

Flexible Now, Built to Grow Later

Whether you're keeping it simple or planning a full onboard air system, this kit works with your setup. Use the manual inflation valves out of the box or tie into an existing compressor when you're ready. Planning to add wireless in-cab control later? It's compatible with that too. Your van evolves, and your suspension should be ready to grow with it.

The product is a great product. After installation was completed and the air added to the air suspension, it raised the rear end of the van about 2-3 inches.A very nice improvement.
Installation instructions definitely need better quality diagrams.
