I am trying to figure out what the differences are between the zex universal dry nitrous kits. Descriptions of the kits give a make and model, but the kit says "universal", so that makes it confusing. Link listed below.

The reason I ask is because my buddy is selling one of those kits and i want to know if it will work on my 5.3L? I don't mind buying new jets, but I need to know if something other than jet sizes are different between these kit?

 

I wouldn't go with Zex, If you check out Harris Speed Works or Nitrous Outlet you will find Dry kits for much cheaper than a Zex kit. I have a dry kit from HSW and Window/WOT switch form N.O. and I love my kit. Can't go wrong with either.
