Note: This kit is for trucks where the upper jounce bumper pad sticks out 1' below the frame. All Toyota kits need at least 5'' between the tire and the frame and fit only with stock wheels and tires.
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 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 for peace of mind and enjoy a comfortable ride without air when not towing.
Customers can choose to buy 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 avoid bottoming out due to loss of air bag pressure, a rare event that could damage the air bags or the truck frame. It's like 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 HP100158 ALPHA HD air bag.
