Features to know about
Control and Cushion When It Counts
When the load gets heavy, your truck needs more than just rear springs hanging on for dear life. Alpha HD air springs add up to 5,000 lbs of rear axle support, keeping your truck steady even when the trailer is loaded, the bed is packed, and the miles are long. No more rear-end sag throwing off your braking and steering, or headlights pointing into the sky. With air bag support underneath, you keep control of your ride even when you're towing a travel trailer or moving a serious payload.
Dial in the Ride for Any Load
Every load is different, and this system adjusts to match. Alpha HD air springs let you fine-tune ride height and firmness with air pressure from 5 to 100 psi. When carrying heavy weight, add air to level your suspension and maintain steady handling. Running without a load? Drop to the minimum pressure for a smoother, more compliant ride without stiffness or bounce. Manual inflation valves are included, so tuning your setup for each trip is straightforward and dependable.
Built Tough for Work and Weather
Air bags are only as strong as their weakest link. That's why Alpha HD bags are reinforced from end to end with heavy-duty end caps, 20 internal support wires, and powder-coated steel brackets. Add corrosion-resistant hardware and thick roll plates, and you've got gear that holds up to real-world hauling through heat, cold, salt, and slop.
Installation That Doesn't Waste Your Weekend
Adding serious load support shouldn't mean losing a whole weekend. The precision laser-cut brackets are designed to bolt cleanly to your truck's existing mounting points with minimal drilling. Just smart engineering that fits the way it should, which is perfect for the DIYer. Manual valves mount through license plate fastener holes or a location of your choosing (which may require drilling). With high-quality fittings, pre-bent brackets, and mounting hardware included, you'll be back on the road in just a few hours without a trip to the fab shop.
Flexible for Today, Ready for What's Next
This kit is designed to work with your setup today and wherever your upgrades take you tomorrow. You can inflate manually with standard air valves right out of the box, no extra parts needed. Already have an onboard compressor? The Alpha HD system connects easily to most existing setups. Planning for an in-cab wireless controller down the road? No problem. The foundation is already built in, making it easy to expand your control options when you're ready.
