Tired of truck sag, sway, and bottoming out? Say goodbye to these problems with the ALPHA XD PRO from Pacbrake! These air bags/air helper springs (with Jounce Bumpers/Bump Stops) come with inch-thick corrosion-resistant end caps and 20 support wires for ultimate strength and durability.

This kit features a bouncy polyurethane bumper in the bag to avoid damage caused by bottoming out. Perfect for those who want the peace of mind of having an internal bumper and covet the ride comfort of being able to run without air when not towing.

Customers will now have a choice to buy a Pacbrake air suspension kit with or without an in-bag bump stop.

Part Number: HP10171-X-J

• 7,500 lbs of load leveling capacity
• 2-hour install time
• Lifetime warranty
• Can be run at 0 psi 

Why did Pacbrake add a bump stop to their bags?

Peace of mind. Customers want a bump stop to prevent bottoming out from loss of airbag pressure, an extremely rare event that could damage the airbags or potentially the frame of the truck. Think of it as an "insurance policy" against bottoming out.

An additional benefit is that you can run these airbags at 0 psi when unloaded for superior ride comfort.

Are bump stops necessary?

No! For those that require max travel in their airbags, to raise and lower their rear end to pickup trailers or boats, or for those that take their trucks off-roading, airbags without bump stops are recommended.

For those that desire maximum bag travel, a great benefit when offroading, towing and launching boats, or for those that constantly need to lower their rear to pick up trailers, consider the HP10171-X ALPHA XD air bag.
