I called Jeff, and the current price PP997900 air bag is $246/ea, 1-2 week lead time.That's not correct for the combo unit. Jeff was very patient about getting this clarified: PP997900 is for the bag only. It was ~$500 for a shipped pair. He had a separate number for the shock (PP954900) and it is definitely NOT included with the PP997900. The combo unit was something like $439 each, it was ~$900 with freight if I had pulled the trigger.
Ohio Hydraulic even list the two components together on the same page with their individual prices:
The part number for the whole "combo unit" is PAS259. 10+ week lead time.
