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

[Rocket Man]

I did H3 mounts. Bolt on like stock. No complaints in the 30 miles I've used them

I always get it confused, H2 or H3 mounts. I wonder what they used on my bagged and bodied Silvy since they had to lower the engine in the bay in order to get the hood to close. Might be something else entirely afaik.

Guy at the machine shop told me they were gtg as well.
did you just put on plain, or use some copper sealer spray?

Put on as-is. The heads were resurfaced since they were shaved a little for compression, the block deck was just scraped clean with a Razr and lightly buffed with a super fine Roloc disc. Same way I've always done and never a problem.

Oh. Just did oil change on mine in driveway. Found sway bar end link destroyed so replaced both fronts. Next up will be power steering fluid replacement and brake fluid etc. then trans service. Going down my list. Still need to do that damn charcoal canister clean up.

I think it's H2 mounts, as the H2 had the 6.0l and 6.2l engines.

H3 came with like a 3.5l

The H3 was also available with the 5.3. I don’t know what fits our trucks, though. Some day I’ll probably need to know...

Just to clear up confusion.

The mounts that fit our trucks are for the passenger side of the Hummer H3 Alpha, which came with the 5.3l. You will need two passenger side mounts to replace both mounts in our rigs.

And they work beautifully I might add.

Bringing back more memories man.
