I got the cheapest price for a set for a 14 JGCL by searching for the OEM part# at their site.. Paid $80. for a set of four. Using them right now. They are factory OEM parts. Part #56029398AB. No syncing was necessary- just put them on with new tires and wheels and the TPMS system picked them up almost immediately
