Used these on my last 6.0 rebuild with brand new Melling lifters. I just took the heads off after 7 months of running because of a slight head gasket leak. Trays still looked great and fit tight against the heads but either they lost tension on the lifters or the lifters themselves lost the tight grip on the trays. Lifters were from Autozone so I'm still giving this 5 stars because I'm not sure which are to fault.

My daughter's Tahoe had an AFM lifter fail. So, I decided to do a DOD/AFM delete because it was likely the other lifters would be more failing soon, too. I decided to gather all of the parts necessary vs buying a pre-assembled kit. I didn't cheap out on quality and still saved ~$130 over the TSP kit with fewer necessary parts. After tuning out the AFM, the Tahoe started right away and ran like new with no ticking and no CEL.

Helped the lifters in my ls stay nice and seated where they are supposed to be. A good idea to swap them out anytime you would have the heads off if the old ones are worn out.

They look like the original ones, nice tight fit with the lifters, would buy again

Lifter trays should always be replaced any time you have the head off as cheap insurance against dropping lifters when doing a cam swap later. These trays hold the lifters pretty securely so make sure that you press down on the pushrod when reassembling to make sure the lifter gets pushed down.
