Some Freightliner air bags can be found with the number 1T15ZR-3 on the rubber.
If your air bag has this number, check the diameter of the base. If it's 9.75",
you'll want this air bag. If it's 10.62", you'll want part number 280-9780 or
280-9781 shown below. The only difference between those two air bags is the base material.
