Tired of truck sag, sway, and bottoming out? The Pacbrake ALPHA HD PRO is the solution! These air bags with Jounce Bumpers come with 1 - inch thick corrosion - resistant end caps and 20 support wires for great strength and durability.
The kit has a bouncy polyurethane bumper in 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
Peace of mind. A bump stop prevents bottoming out due to loss of air bag pressure, a rare event that could damage the air bags or truck frame. It's like an 'insurance policy' against bottoming out.
You can run these air bags at 0 psi when unloaded for a more comfortable ride.
Are bump stops necessary?
No! For those who need maximum air bag travel, like when picking up trailers or boats, or for off - roading, air bags without bump stops are recommended. Consider the HP10391 ALPHA HD air bag.
