It fits all trucks, even those with 5th wheel hitches, except for ones with Curt 5th wheel mounting plate kits. Say goodbye to truck sag, sway, and bottoming out! These air bags come with 1 - inch - thick corrosion - resistant end caps and 20 support wires, offering ultimate strength and durability. Inside the bag, there's a bouncy polyurethane bumper to prevent damage from bottoming out. It's perfect for those who want an internal bumper and a comfortable ride when not towing.

Using your Pacbrake ALPHA HD PRO air spring suspension kit is easy. First, install it according to the instructions, which should take about 2 hours. This kit is designed for 2022 - 2024 GMC/Chevrolet HD trucks with 6.6L Duramax engines, but remember it won't fit trucks with Curt 5th wheel mounting plate kits. When towing or carrying heavy loads, you can adjust the air pressure in the bags to provide up to 5,000 lbs of load - leveling capacity. If you're not towing, you can run the air bags at 0 psi for a super - comfortable ride. The in - bag bump stop is there to protect your air bags and truck frame from damage in case of a rare loss of air bag pressure. However, if you need maximum travel for your air bags, like when hitching trailers or going off - road, you can choose the version without the bump stop. As for maintenance, check the air bags regularly for any signs of wear or damage. Also, make sure the end caps and support wires are in good condition. And always remember, never exceed the manufacturer's recommended Gross Vehicle Weight Rating to keep your truck and the suspension kit in top shape.
