I have Three (3) OEM GM TPMS Sensors Part # 22854866 and Four (4) OEM stems. Sorry I don't have an even 4 of each, I used one
Everything is completely brand new and unused but I took them out of the original bags when I stored them. These sensors work great with the G8 and were bought new by me to replace all the TPMS sensors in my winter set. Only got around to replacing 1.
Anyway, asking $100 shipped to your door for all 3. I think a fair price considering one is $60 - $70 each. Please shoot me a PM if you're interested. ready to go anytime. Thanks for looking!
