2884062 is the correct kit for pre-2019 TS111 engines... it is priced the same as the 2019 kit - (I do not see any common-sense in that detail.)The part number is 2884062 . Description K-ST3,IND116
That would explain something about the supply shortfall... But says nothing I can discern about pricing and strategy unless they are changing the parts again or are having compliance issues with their flash.probably using the newer kits (for the 19's) or should I say lack of kits for production... probably won't have enough inventory until about Feb 2020 when the second run of production for the 2020's will be about wrapping up..
Pictures and elaboration please... This valve-spring problem has been experienced and reported by others, more factual information can help us all.I had the BBK installed in January and put a little over 4000 miles on the engine and last week it blew a valve spring. It was the new kit but not sure if the kits had the new high lift valve springs in them? Part # 7045087. Does anyone know?
