I think because 3.42 and the V8 are only available as part of the Max trailer tow package.

Welcome to the forum!  You ill find a lot of good information on this site!  I believe Chad's answer is correct and that the 3.42 is part of a package and not specific to a size of wheel.  You will find any of GM's engine/transmission/differential combinations will confidently handle the payloads and towing power specific to the truck. For example, If you need a truck to tow an 8k lb. trailer, then look for the ratings of the one you have in mind.

Still not sure why GM does not give us more gear options like the rest of the big truck guys do. 99% chance you have 3.23 and not saying 3:23 is not good enough or adequate enough because for majority of us the 3.32 does just fine ( thank you 10 speed ) . I’m just saying a low mid, high, gear option would be nice.  I’ll take mine in a 3:73! 🤩

Don’t tell GM but I put 22s on my Max Trailering truck with 3.42s. Nothing has blown up.

 

If I had to guess there’s a ride or handling consideration that excludes the NHT trucks from having 22s. But I dunno. Mine rides great.

My 2016 came with 3.42 axle.  5.3, 6 speed, no max tow, 20" wheels.  My 2019 also came with the 3.42 axle, but it's got the 6.2, max trailering package and 18" wheels..

Im not 100% sure on this, but it seems when i bought my 20 HC 6.2 Max Tow, 20 inches was largest option on it because of tow weight restrictions on 22 inch tires that they offered, 22 inch tire was to thin.......I wish mine had the 22s as i think it looks nicer, but not end of world.

How do you like the 6.2? I just sold my 5.3 2018 Sierra and was going to wait on the 2022.

I love it.  Great truck and engine.  Now when i drive my wifes 5.3 suburban it feels slow and i hate the shifting compared to the 10 speed in my truck. It pulls my 31ft TT 8500lb Gross really well.  Last week i added some Timbrens to help with some sag when hitched up.  Between making adjustments to my WD hitch and the Timbrens, it really feels and pulls like a 3/4 truck in how solid it feels.

I read that 22 in. tires are rated SL meaning standard load which is a lower load rating than the 20’s on the that come with the max towing package. I

      Software Update

      By Chuck FB · Posted

      I am not techy at all but wondered if you have the truck running but sitting still in park as some functions gray out as soon as the truck is moving. I believe in the settings for updates you can choose for it NOT to update and I wonder by chance if maybe that was chosen before and now it won't allow you to chose to press update, I think that is back in the settings menu where it has all the items one wants on or off etc. Also I assume you have a wifi connection and checked that it has some signal strength, not that it would have anything to do with the grayed out updates choice in that case. What I am thinking out loud of here may be be of no value but thought I would suggest it, sometimes it can be the simplest thing that resolves an issue.

      Dave's Auto (custom engine builder) tear down of L8T

      By Chuck FB · Posted

      The so called rare failure that some certainly liked to tout ( die hard Ford fan boys ) as per the lifter failing and wiping out the cam. Back when it started happening the blame was being pointed to the lifters and honestly I never did hear anything myself conclusively one way or the other on that. Ford themselves in I believe 2024 had a technical bulletin I will call it that came out and for some engine platforms they were reprograming the engines idle speed but also they had a software update for the oil pump which then some time later was said what that software update did as to be increasing the oil pressure at idle. It is a good question if that issue was completely solved as one Ford specialist mechanic youtuber said he saw failures after that time period. Like anything there would be the variables, what oil is being used and the OCI and how much idle time gets put on an engine. I've seen some comments to claim that the L8T isn't so happy with high idle time either but I also know that companies that require their vehicle to idle a lot on the job don't tend to get the oil changed often enough for all those hours of idle time and go off of the odometer.

      Lower trims ( WT, Custom, Silverado ( aka LT )

      By bwiese · Posted

      My 2026 Silv. 1500 WT (reg cab/short bed/4wd) has the 40/20/40 with storage in lower middle seat as well as the fold-down center bolster/armrest.   With the dual glove boxes this is about as much storage as possible in a std cab IMHO. Bill

      2026 Silv. 1500 WT reg cab: how many speakers do I have? Is amp module separate?

      By bwiese · Posted

      I have a 2026 base 1500 "WT" regular cab with basic Chevy "Infotainment 3" 7-inch screen/radio. How many speakers do I have If I want to upgrade? Is the audio amp separate from the radio/display unit]? [I listen to classical and it gets a bit raspy at slightly higher volumes. Don't need a sub etc.] Do I have two or 1 speakers in the doors? etc. Thanks Bill  San Jose

      Bench seat swap for 2021-2024 suburban

      By davester · Posted

      probably won't get a response from that user, as they haven't returned to the site since making that one post.  users don't (at least I don't, and I haven't seen any setting which would notify me via say, email) get any notification other than going to this site, and checking if they got a response on their thread...
