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.

Wide leg snatched waist band
Size: X-Large, Color: Brown Black
These pants are perfect. The material is thin but not see through. They are breathable and are truly wide leg and made well for us tall girlies. I'm 5"8 and I usually wear 16/18 pants. I have a short torso, all legs and these pants fit me perfectly. The waist band is a nice snatch for a body suit top. I'm happy.

Just order them!
Size: X-Large, Color: Brown Black
Absolutely dig these loose, lightweight, flowy cheetah print palazzo pants! I got the XL in brown/black and can't wait to wear them. They are true to size (I typically wear a 16 and have ample hips). Will pair with a more fitted tee, platform sandals a d a jean jacket. So cute and comfy!

Awesome pants.
Size: X-Large, Color: Brown Black
LOVE these pants and have gotten so many compliments. Cool and comfortable. Very wide leg - be prepared for snarky comments but WHO CARES? I say let the haters hate because clearly they are jealous of your amazing pants. The pants are very cute with a denim button down or an oversized tee and some sneakers. I am 5'9" and the pants are plenty long. Not too long to drag on the floor but right to the sole of my sneakers.

Run very big!
Size: Medium, Color: Grey
The pants are SUPER CUTE. The material is fine. My complaint is how BIG they are cut. I’m 5’5”, 165, tiny bootie, and large legs-i ordered a medium- they are so BIG, should have purchased a small but need to have them in 2 days so I will be altering them myself.
