Overview

Eliminate truck sag, sway and bottoming out with ALPHA HD PROTM air bags / air helper springs from Pacbrake, the only brand with inch-thick corrosion resistant end caps and 20 support wires for maximum strength and durability.

Product Description

>> Designed for durability and performance, the ALPHA HD PROTM Series comes with Jounce Bumpers/Bump Stops, a flexible polyurethane bumper inside the bag that prevents bottoming out, which could damage your air springs, and allows you to run your bags at 0 psi when unloaded for factory ride comfort.

>> Perfect for those that 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.

>> 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 our HP10337 ALPHA HD air bag.

>> 5,000 lbs of load leveling capacity*

* Never exceed manufacturer's recommended Gross Vehicle Weight Rating.

Riding on the bumpstops

I bought the "Pro" because I wanted to leave them at 0 psi when I'm not towing. The Pro has a bumpstop inside to facilitate this.
At 0 psi, my 2019 Ram 1500 Classic 4x2 is riding on the bumpstops. It is super uncomfortable.
Maybe the 4x4 truck has more room in this area to allow some travel before hitting the stops, but mine is on them at...Read More

ride height. At least that's what I'm feeling. Super bouncy and stiff even with no air in the bags. It seems to help a little to put a few psi in them, but that raises the back of the truck which isn't ideal.
The build quality seems really good and they bolted in easily, FWIW. Read Less

Why did you choose Pacbrake?:

I was bombarded with advertising from PacBrake saying how much better the build quality is. Honestly I would rather have to replace parts now and then than be uncomfortable for 200k miles.

Hello Geoff - thanks for the communication over the last few days and I was glad to hear we were able to come to a resolution.

Unfortunately, with this particular Make / Model of vehicle, there is not much room for the installation of the air bag, limiting travel. However, this is also our best-selling air suspension kit, so most find the support a welcome addition!
