Dumb lifter question

[1500guy]

My lifters went. Dealers been great and fixing me up. He said he had “4” and needed to source the other 4. I said your doing both side right? He said yes.  
 

I didn’t realize there are 16 total.  How are these sold? It sounded like he was needed 2 “sets” and was maybe referring to number of cylinders vs. lifters. 
 

basically I’m now questioning whether he’s replacing ALL lifters

Wild guess, but with cylinder deactivation, I bet there is 2 cylinders worth on each side that they are replacing. So a total of 8 lifters.

You can order them from GM in quantities of 1 but if you stock them GM ships them in quantities of 4 depending on how many you stock. If they are only doing the right bank which they probably are if it is warranty then they will replace all 8 lifters on the right size most likely. On these DFM trucks they are all the same lifter unlike last generation that had 8 AFM lifters and 8 non active lifters. These lifters are a pain to get right now as well, currently on backorder and have been on backorder for months

Hmmm, I will give them a shout now. There’s a TSB, they are supposed to replace both banks so I want to make sure they do that

I don't think warranty will do both sides unless truck has under 8,000 miles and meets model break point dates. Then and only then I believe you will get all 16 lifters. Did you call them and see?

Iirc, also needs to be a 6.2.  The TSB for 5.3s only said to replace what needed repairing.

Correct FYI they replaced all 16 lifters, the guides, a push rod and all the other junk that ya touch doing that job. Back in my hands in a week. Running good so far. 
 

Was unfortunate but can’t complain about how the dealer or gm handled it.

 

I have a copy of the tsb if anyone needs it
