warning to those installing air bags
Ordered the Air lift ultimate 5000's for helping out when towing our fifth wheel. Install was easy, straight forward.
However I've had 2 failures where the brass bushings/nuts inside of the bags have been pulled out, severing the airline and it's fitting.
Prior to the bag install, I put the rough country leveling Kit in, which included a small rear block spacer for the leaf springs, about 1.5" thick. This small amount was enough to put the bags out of their operating limits, and when driving unloaded, was actually pulling the bags apart/stretching them, causing the failure.
In conversations with Air Lift, they said the bags need between 5-7 inches at vehicle rest (unloaded) between bracket faces to ensure proper operation and longevity. I measured, and sure enough, ended up with 8.5"
The solution from them was to purchase an air bag spacer, made by them and various manufacturers, to correct the difference, most come in 2" increments.
I must mention however that the company, Air Lift, has been excellent to deal with, and are sending me replacement bags, fittings and hardware at no charge, to ensure I'm satisfied, even though the failures are a result of my modifications. Highly recommended.
Don't take advice from me. You'll end up drunk.
