Cab air bag springs install on International.

[Rig Wrench]

I've seen the local kw dealer charge close to $800 to swap the cab shock on a W900 daycab. Definitely something you want to do if you have the trans and driveline out. On a KW I've found it easier to pull the whole cab ride assembly to change it. Usually the shock bolts freeze, can be a nitemare. Pete's are cake. All external. Those are what I usually work on if it helps anyone
