NON AFM DOD Disable Kit with Camshaft Lifters, Timing Chain, Oil Pump, Head Gasket Set for 2007-2013 Chevy Silverado 1500 Tahoe GMC Sierra Yukon Buick 5.3L

does not work as they say it will mess up my truck

I rebuilt my 2011 Tahoe 5.3l flex and thought I would save you time to let you know what else you will need. If you are doing a 2007-2014 Chevy 5.3 this info is priceless.*Earlier generation timing cover.*Camshaft position sensor.*Camshaft single bolt- Chevy dealer did not have this bolt nor the auto stores. I found it at GM, it was thier last one and they said it is for a Pontiac.*Oil pan bypass bolt.*I got oil tower plugs (pound in), not necessary but for piece of mind.*AFM/VVT delete the ECU. I sent mine through the mail to LT-1 Swap. Put it in the truck and it required no further programming.*I had to modify my oil pressure sending unit filter as the valley cover is too shallow for the full depth of the filer. The filter is too long.*Red Locktight.*Blue Lockight.Above are the things you will have to get to accomplish your rebuild.Below, you may consider replacing while you have it taken apart.*Water pump.*Spark plugs.*Belts.*Oil filter.*Valve springs (I did not replace my valves or valve springs).I picked up a Dewalt electric ratchet at the beginning of my rebuild. Pretty sure it saved my life.Flywheel tip; I picked up a flywheel holder. It is installed in place of your starter. This tool was worthless to me and Ive heard the same from others. I wrapped my harmonic balancer with a bicyle inner tube, looped a tie down around it and tightened it to the frame to remove the bolt.I hope this helps. In the end my engine runs better than before the lifter failure.Good luck!
