Air suspension dump valve

[biscuits and gravy]

overdriveonline has an Internet article with photos on how to install a manual air dump valve on an international. 4 states trucking installed the dump valve and they covered the article.

I think the truck parts supplier named anythingtruck, sells them for about 40 or 50 bucks. I bought one a few months ago and put one on. It was a simple job to do and and I would rate the skill level that it took to do at a beginners level of 2 beers and 3 or 4 cuss words.
