Has anyone successfully lifted with the 3.5” RC and have the rear mono leaf? I have posted about this before… turns out you get a whole bunch of clunking back there after a while. U-bolts torqued to spec. Anyone?

You can keep your leafs. There’s a few kits now. Rough country also sells rounded ubolts at 3.25” wide which fit perfect. There’s a 1/4” plate under the leaf that’s 3” wide to give the leafs full bearing for the axle. Keep that. Put a block under it. RC nylon blocks seem to fit well. Yes I know you shouldn’t stack blocks but I’m not considering that plate a block. It has lips and groves to hold it in place. Without it, the blocks are only 2.5” wide which I’m sure isn’t good for the leaf. Do at your own risk.

Has anyone done this yet? Appears all the mounts on the frame are the same, would likely need some shackles, the additional bolts, etc.

Besides cost... is this even a fair comparison? I'm guessing the LTZ pushing near 25-30k cheaper and you'll be saving a buck but everyone is going to pick the AT4x if cost isn't a factor.

Depends what size tire the AT4 came with vs the Denali.. if the AT4 has stock 32" tires and Denali 33", than no, the spares won't be the same size.

I tried, doesn't work. Did it the same as mine. Mine worked.

Autostop eliminator works just fine on mine and the install really isn't that bad. Sure a few more panels but straight forward. I did it in my 21 and 22 refresh, no big deal.

Worked for me, 2022 Sierra. Awesome! Thanks.

Don't see why not, the bottoms are identical, the backs may be the upgraded storage version but I replaced my regular back with a storage back model in my 21 Silverado.

Anyone see rear block lifts available yet for this new single leaf set up?

Yeah, that's just regular leaf springs. GM really turned me off by not advertising the new polymer leafs at all and just dropping them in the trucks. Seems to be Chev LT models and GMC Elevations without max tow but with x31 or z71 that are getting them.

I was concerned about taking apart the new refreshed dash but it actually came apart quite easy. Go with the better product. Get the eliminator.

Well this was all extremely informative. Can't believe they made a system that doesn't require any human input! GM did something right finally. Going to be getting sensors on my winters in the next few days to avoid the light.... been looking at that for years in past cars and I'm done with it. Thanks for all the info.

Was at the dealer yesterday looking at some take off rims. Came off a 2022 limited model. Parts guy is saying the tpms do no not talk with the software in the refreshed models even though they are both 433hz. Anyone run into this issue? I know the 18's and older used 315hz sensors which causes an issue.

The heater plug in your bumper plugs into another harness behind the bumper. It has a thermostat built in. I'd suspect it's the thermostat that's the issue. You can order the harness and install, nothing too difficult as you already have the layout of where it needs to be.

Fuse 26 passenger side. Go on amazon and get a micro3 fuse tap. You may need to shave it a bit to fit but it works.

Literally threw mine out last week as I traded in my Silverado. Hope you can find some for free, someone else must have kept theres.

Some added photo's. Harness may not be exactly where it needs to be, but the plastic mount at the front is, shock tower attachment and where it comes back down to the side of the engine. Seemed to fit perfect for length and it not around any moving parts. Bit went under there, car wash this morning. Block heater harness plugged into the heater. I ended up bending the metal tabs back so they don't rub against the heat shield on the sensor beside it. Behind the bumper, harness that passed through to plug into. Plastic mount clips in right about this area. Hard to see, but it sits ontop of the bumper frame here. That's the back of the drivers fog light. There's two small holes in the framed under the body mount here, the plastic harness mount lines up with these, ones a christmas tree clip, the other just a line up pin. Also has a oval style christmas tree clip ontop, you can sorta see it sticking through to the left of the body mount from above. This is the plastic mount with the thermostat built into the harness sitting on the bump framing looking towards the back of the truck. Top of the shock tower, clips on one of the tower bolts and right beside as well.

I ran a plastic one for 10 yrs in my 2012 Sierra. Pull it out once in a while and clean under it. I live where they spread salt 4-5 months of the year and never had rust issues (Also had it Krown'd yearly). Spray in is preferred but I have no concerns with a plastic liner.

Thought I'd make a post on this since there is basically no information out there. If you live up north and want to install a factory block heater on a 19-23 Silverado or Sierra, GM doesn't have a kit listed anywhere for a block heater. Instead order the following kit for the Full Size SUVs 84916467. It comes with everything you need including an extra small plastic bracket you can throw out. Cheaper than ordering the parts separately as well. There are no installation instructions but the hardest part is figuring out where to route the wires. Start at the front and mount the black plastic mount where the wire appears coiled and zip tied. This mounts on the bumper frame, will try and get a photo soon. It'll continue to feed on the drivers strut mount and back down. Find the clip holes along the way. You can pull the 17mm hex plug towards the rear of the engine. It's fairly obvious on the drivers side. If you do so without draining coolant, have a big catch bin and don't lay under it or you're in a for a soaking. You'll lose about 3 quarts, easy to fill back up later on. Screw in the block heater, tighten to around 37-40 (seems to be the consensus). 26mm socket (I believe you can get away with a 1 1/8") Plug it in and fill back up the coolant as you normally would. Hope this helps. Like I said, hardest part is figuring out the route for the wire and where the plastic mounts to the bumper frame. I did end up zip tying some extra spots.

Switched back to a Sierra (and a 5.3) a few weeks back. The 3.0 was nice but always had concerns in the back of my head. Best part, no DFM on the 5.3 from factory.

I don't run tpms in my winters, message pops up when you start, hit the button to go away. Light stays on but still cheaper than adding them.

So annoying, can't use my blocks from my 21 Silverado now...

It looks possible to put a block between the axle and the plate under the mono leaf. Just need to size the u bolts. They seam to be 9/16" but it's measuring 3 3/8" between which is not a common width.
