Tired of truck sag, sway, and bottoming out? Say goodbye to these issues with Pacbrake's ALPHA HD PRO! These air bags/air helper springs (with Jounce Bumpers/Bump Stops) have 1 - inch - thick corrosion - resistant end caps and 20 support wires for great strength and long - lasting durability.
This kit has a bouncy polyurethane bumper inside the bag to prevent damages from bottoming out. It's perfect for those who want an internal bumper and enjoy a comfortable ride without air when not towing.
Customers can choose a Pacbrake air suspension kit with or without an in - bag bump stop.
Why Pacbrake added a bump stop to their bags
Peace of mind. Customers want a bump stop to prevent bottoming out due to loss of air bag pressure, a rare event that could damage the air bags or the truck frame. Think of it as an 'insurance policy' against bottoming out.
Another benefit is that you can run these air bags at 0 psi when unloaded for a super - comfortable ride.
Are bump stops necessary?
No! For those who need maximum travel in their air bags, like for hitching trailers or boats or off - roading, air bags without bump stops are recommended. Consider the HP10604 ALPHA HD air bag.

This air suspension kit is designed for 2022 - 2024 Toyota Tundra 2WD/4WD models. To install, it takes about 2.5 hours. When installing, make sure there's at least 5 inches between the tire and the frame, and use stock wheels and tires. The kit comes with two options: with or without a bump stop. If you want peace of mind and protection against bottoming out, choose the one with a bump stop. It's like an insurance policy for your air bags and truck frame. And when your truck is unloaded, you can run the air bags at 0 psi for a super - comfortable ride. But if you need maximum travel for hitching trailers, boats or going off - road, the air bag without a bump stop (like the HP10604 ALPHA HD) is a better choice. Remember, never exceed the manufacturer's recommended Gross Vehicle Weight Rating. For long - lasting performance, keep an eye on the corrosion - resistant end caps and support wires. The kit has a lifetime warranty, so you can use it with confidence.
