When the load gets heavy, your truck shouldn't feel like it's fighting you. These air bags help you stay level, drive steady, and stay in control so you can tow with confidence and handle heavy loads without second-guessing your suspension.
Whether you're towing a fifth wheel camper, hauling materials, or running tools to the next job, the rear suspension on your Silverado or Sierra can only do so much on its own. Alpha XD air springs add up to 7,500 lbs of rear axle support, helping your truck stay level, controlled, and confident under heavy load. Designed for 2020–2025 2500/3500 trucks— SRW and DRW alike—this system works with factory 5th wheel hitches and keeps you from squatting out, losing stability, or blinding oncoming traffic with tilted headlights.
From a loaded trailer to a light weekend cruise, every haul is different. That's why Pacbrake gives you 5 to 100 psi of adjustability. Full load? Pump it up. Just dropped the trailer? Drop the pressure for a smoother ride. With simple manual inflation right out of the box, you can dial in support and comfort for whatever the road demands.
Heavy-duty towing means your suspension components need to be tougher than the terrain. Alpha XD springs are built with one-inch thick, corrosion-resistant end caps and 20 internal support wires for serious strength under pressure. Roll plates prevent chafing. Powder-coated brackets fight back against rust, salt, and abuse. Whether it's heat, snow, or a muddy jobsite, this kit is built to last through it all.
Designed to bolt directly to factory frame points, this system installs cleanly with no drilling or welding required. That means fewer headaches for you, and no compromises on your truck. With laser-cut brackets, high-strength hardware, and full instructions included, it's a perfect upgrade for weekend wrenchers who want professional-grade results.
Start with manual inflation today and upgrade to an onboard compressor or wireless controls later—no need to replace anything. Alpha XD systems are compatible with most aftermarket air management setups and are built to expand with your build, not limit it.
