Description

Note: For all truck bed lengths. Will NOT fit models equipped with Adaptive Ride Control. AT4/Trail Boss - requires 2" spacer.

Tired of truck sag, sway, and bottoming out? Say goodbye to these problems with the ALPHA HD 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.

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 air bags, to raise and lower their rear end to pickup trailers or boats, or for those that take their trucks off roading, air bags without bump stops are recommended. Consider the HP10340 ALPHA HD airbag.

Easy to use
Color: black
This dash cam was very easy to install and the video quality is super clear, even at night. I like that it records both the front and inside of the car, which makes me feel safer while driving. The screen is simple to use and the camera works smoothly without issues.

Great camera! Great quality!! Easy to use!!
Color: dark
I purchased this dash cam for added security while driving and when my car is parked, and I’ve been really impressed with how well it works. The video quality is sharp and steady, and it captures way more detail than I expected from such a small camera. Both the front and inside views record clearly, which makes it great for everyday driving. The night recording is one of my favorite features. Even in very low light or complete darkness, the footage comes out clear and easy to see. Faces and surroundings show up well without any harsh glare, which makes a big difference at night. Setup was simple and didn’t take much time at all. It sticks securely to the windshield and hasn’t moved once. The menu is easy to understand. I also like having features like loop recording, impact detection that saves important clips, motion sensing, and parking mode for extra security when the car is off. Overall, this dash cam does exactly what I was hoping for and more. It’s easy to install, reliable day and night, and makes me feel much more comfortable whether I’m on the road or away from my car. I would definitely recommend it to anyone looking for a solid dash cam.
