Gen V 14+ L83 L86 DOD Add-On Parts Kit

These are recommended items to replace when deleting the DOD/AFM from your 2014-2019 GM Truck or SUV with the 5.3L L83 or 6.2L L86. These items generally do not come in the delete kits but are the other parts that are recommended to be replaced while you are doing the delete.  This kit includes: GM Oil Pump 12686433 GM Timing Chain 12646386 GM Timing Chain Tensioner 12630107 GM Fuel Rail Cross Over Tube 12677002 GM Intermediate Fuel Feed Pipe 12677004 GM Fuel Pump Gasket 12623308 GM Fuel Pump Lifter 12642273 NOTE: GM has switched suppliers for their timing chains and the new chains have a different part number. We are getting mixed inventory on our GM orders with new and old part numbers. The new part number is 12646387 and the old part number is 12646386. You may receive one of the new part numbers in your order. Once GM stops sending the old part number we will update this listing to reflect the new part number.
