FWIW my passenger side was not torn, but possibly leaking. With just driver side replaced, it felt great!
Both H3 mounts installed on a stock engine, I do feel a very slight increase in vibration through the steering wheel at idle. Not bad at all, but not 'zero' difference.
I like the added durability of the H3 mounts, so am still happy I went with them, despite being overpriced...
Replacing the mounts was really NOT BAD at all!!
The number of screws and parts that need removed are small.
Only a couple are harder to reach, and the frame bolts feel like they are threaded into locknuts so it is a little slow.
BUT, zero surprises! Once you have the right length of stubby extension and/or swivel joint, you are set.
Get intimate with your strut towers, strengthens the owner/vehicle bond.

If you have 4WD get ready for a real fun-fest. I changed my driver-side mount this weekend. Spent about 12 hours and really tore my left arm up badly. See my post. Beware the black rectangular connector block for the ECU/Ignition harnesses (between radiator and #1 cylinder). The exposed corner is razor-blade sharp. Took me 12 hours and I have all the wobble sockets, extensions, airtools, etc... Do yourself a BIG favor and find a shop that will do it for you!

Funny, I have a 2009 4wd tahoe and somehow dodged that whole nightmare TWICE having replaced a broken mount on my 5.3 then swapped the engine to a 6.2.
It's much simpler with the wheel off and the fender liner removed.
yep, mines a 4wd. ugh. I have a loose plan to do it tomorrow. I might just have to pull the wheel and liner out. I have decent tools here, but most of the oddball stuff is at work. plus no top side creeper here.
throw in my battery is in the left front plus a few extra things and a aux fuse box. I'm not looking forward to it but it needs it badly.

I will say, it's really a nice feeling to hit the accelerator now and not hear/feel the clunk!
Hope yours goes better than mine did! Kevin

I have to say that I didn't find it to be too bad. I'm built like a grizzly bear with similarly-sized paws, and I did a handful of things that helped:
1/ I separated the steering shaft. It was a pain to do and took some patience, but it improved access significantly.
2/ As others have said they did also, I took the front wheel off along with the fender liner. Takes 10 minutes to do both. Game changer.
3/ I removed the heat shield from the exhaust manifold after patiently waiting for the penetrating oil to do its job on the bolts.
4/ I used a block of wood under the oil pan with a good quality floor jack that made it easy to support the engine and carefully raise it incrementally as needed.
5/ I cut away the heat shield from the motor mount with a pair of tin snips to get better access to the bolts.
6/ I used a wobble joint on the socket wrench.
Having done the job now, I wager I could do it again in a couple of hours and less than 3 beers, taking my time.
It's also a really good time to change the engine oil cooler lines, if so equipped.

Not to get too political but E-lections have Con-sequences..... lol
my guess is since it's a discontinued H3 and it's literally the only mount listed for those trucks, there's no auto parts store replacement and they don't seem to fail. gm is probably like why do we keep running out of stock on these parts. (no clue who the vendor is) I'm curious what's going to happen in a few years when it hits the time gm stops supporting parts for for the H3. I guess we'll all have to go aftermarket poly at that point.
inflation is real, but this feels different.
on a side note I didn't get to mess with mine this weekend. maybe next
