What did you do to your NNBS GMT900 Tahoe/Yukon Today?

I honestly have no idea. This is the first time ive had to deal with LS motor mounts. Is it the H3 alpha mounts since they came with the 5.3 or just the regular H3 ones? I guess i need to look into it.

These are the ones i bought,

I think so. I have had my blower and trimmer about 15 years with no notable problems. It’s good stuff in my opinion.

I got the echo trimmer 2 years ago, love that too. Especially the fast line load gimmick.

called the machine shop to ask about my assembly balance.
Figured with my luck it was sitting there ready but nobody got around to picking up the phone.

nope, but they said they would get to it the first of next week.



I need to check the clearance/gap on the piston rings.
I really need one of my pistons in order to square it up.
Read I could use a bolt...
Maybe i'll try that...
It's going to be another boring weekend for me.

Wife is abandoning me too, so probably yard work and

I love my hydraulic mounts in my Tahoe and don't care how many times they may need replaced... The smoothness they provide is something I'm not willing to sacrifice. These mounts make the engine barely noticeable while at an idle, but my GMT800 I can tell the difference in mounts. I know some members will disagree, but I'm giving my honest observations, since I own one each GMT800 and GMT900. I used to have a OBS 1995, 7.4 2500 Suburban and I remember feeling everything the engine was doing through those shit ass mounts back then

Lol. I was just sitting in my Silverado trying to post but my phone was jumping around in my hand so bad I kept hitting the wrong keys. The cam I installed has so much lope it’s crazy. I don’t care about smooth, I wanna know I have a V8.

Watched some youtube video about valve springs today.
THey mentioned the overhead claw type compressor i have, and said don't use it.



apparently it can damage the springs or some nonsense.

they also said to toss springs if you drop them on the floor.




Yeah so i totally just ordered this type of valve spring compressor for my new springs.

nice thats the side i need too. should do them both but we'll see. guessing the h3 mount is a solid/traditional mount? i didnt think my NBS felt too bad at idle.

I also opened my box of "gm" springs that i got from summit...
I was expecting some sort of "gm" type badging.

Just a boring box, and each spring inside of that box is bagged with a "made in Mexico card"


Yeah, i paid extra for the "GM" ones.

Someone will confirm, but I think the H3 passenger side mount is good for either side of these rigs.

for our trucks, both sides are the same pn as i posted.
And yes, solid mount.

as for how it feels, no idea!
mine are still in a box.
I look at it as "i don't want to do it again any time soon"

but my driver side was totally shot when i removed it.
I never noticed anything.
