Air dryer works great but description does not explain what is necessary to install. Overall it works great and I'm very happy with the purchase.
Product works great, all the fittings were interchangeable and went well...
Okay so I have a 1986 m923a1 with the nhc250 Cummins. Stock air dryer making all types of hissing noise While driving. I called mid west and explained what’s going on automatically told me this is your fix. I was wondering why the shipping cost was so expensive. When I received this box let me tell you this is a massive air dryer. Totally worth the 299 totally worth the $36 shipping and handling to Florida. The construction the weight the material it is outstanding.
