I just got my new truck and the dealer is leveling it to keep my warranty. I did a bunch of research and there’s a few out there that won’t work with the 3.0 apparently. They’re using readylift and mine will be the first they’ve done. Anyone have issues? Heard the CV shaft and shock can touch with the wrong kit. If you have what size tire are you running?

Leveling is a new term to me in this context, can you explain?  Thanks. 

Most trucks have a lower front end or a “rake” and a leveling kit raises the front end to make the truck level or closer to level depending the size you get. 2” is the most common I’d say. I did find the answer to my question because the bottom strut style leveling kits don’t work with the diesel. Rough Country makes one for the diesel so going with that. It’s to get it level and help fit bigger tires without a full lift. I can’t do a lift or I void my lifetime powertrain warranty.

What truck and trim did you get with the 3.0?  The GM (trailboss/at 4) should be fine as you can get the AT4 with the 3.0.

I got it figured out. Rough county makes a kit that works apparently that’s either new or somehow looked over it and the dealer also couldn’t find it originally. It’s the RST trim package.

I just bought a 2021 Silverado LT yesterday; the 5.3. Looking into leveling it also. Do you know if the kit you found also works for 5.3 by chance? Or can you can you share the part no./kit no.?

It might but I’d just google a leveling kit. There’s a ton out there. The issue is the diesel motor with 99% of the kits. Some come with shocks and there’s different styles so I’d research it yourself.

I went with the Zone off-road 3.5” kit. It’s a bit more than a “leveling kit,” but I haven’t had any issues with it in about 3k miles.

The dealer had a ready lift kit in mine when I bought it, it was ok.  I have switched to Bilstein shocks all around and removed the level kit, since you can adjust the front up to 2.5".  Way better ride and handling with this setup

There's pretty much nothing different in the 3.0 vs any other sierra when it comes to lifting outside of the fuel lines needing a small drop bracket to clear the driveshaft if you go 6+ inches of lift.

What's different about the front end on diesel trucks that make them difficult to level?

Makes sense to me but I don't understand why this thread exists, then.

I was wondering that myself, so I figured I'd drop off some knowledge here before some misinformation starts flying around lol

      OCI, not when but why?

      By KARNUT · Posted

      What’s missing in all this is patience and investment in the future. Buy a 170K starter home. Ten years later sell it invest in a more expensive home. Eventually you’ll have a 600K home and pay starter home payments. Buy a starter car. Maintain it well. Save the payments after it’s payed for then buy an expensive car if you desire. Buy a tumbler make your own coffee, pack your lunch. Cook your own dinner. Most importantly take care of your car.

      People mislead themselves. Statistics are highly useful indicators.   Here's the tie-in to this thread. If an oil sample tests shows a wear indicator of 7 using cheaper ACDelco oil, and a wear indicator of 2 (lower = less wear) using a particular brand of Mobil oil, and wear has a linear relationship with engine lifespan, anyone could assume that Mobil is reducing wear by more than 50% (let's just say a 200% reduction for you red state people trying hard to do math) which leads to increasing engine life by 2x. Perhaps, in a vacuum, by itself, when dreamed by AI.   Yeah?! That's what the statistic is saying, isn't it?   No, it isn't. It didn't come out and say engine life is doubled. That's a very bad assumption, and a case of severe myopia by assuming something potentially untrue about the only data point in focus.   Average cost of a new car is 50k. You bet it is.   The median cost of a new car is more like 35k. Expensive cars are skewing the perception that "average" now means a $50k price of entry for a very average automobile. And that's not true. People who don't understand statistics twist the living heck out of them to mean all sorts of things they don't actually mean.   "Average" new car payment is $1000/month. Yep, it is. And in that number are all the $35k new car buyers who bring significant equity, and the $25k new car buyers who finance the car for a month just to get a rebate, and then pay it off. Know what isn't in that number? All the payments made by people who don't finance a car.   Picking one's own data point (don't have a car payment, never paid $50k for a new vehicle, my house cost $170k, I afforded a middle class lifestyle on $4.50/hr) is just a data point. Just like earning $25/hr in an area where the median home price is almost $1 Million is a data point. In fact, it's a lot of data points given that 80% of the US population lives in/around major cities. They're not idiots; the vast majority of them do it to make a living because that's where the big money is.   The highs have become higher, lows have become lower, and how your personal mileage varies is not truth for an entire country. At the same time you can't NOT acknowledge the data. While it doesn't paint YOUR personal picture, it certainly tints the reality that you also live in, as does your single data point.

      Poll: Does your truck have the rear window leak?

      Glad you had success with it. I did as well, but about 5-6 months later it returned. Tried again, same result. This was after the dealer made several attempts and never even got it to slow down.

      Will not stay in Reverse

      By TheGeek · Posted

      I have a LTZ and it has the shifter in the console, which I like, but, every now and then, it will not stay in Reverse. I go through all the motions, hold the button in, push the shifter forward and watch the dash.  The big red R comes on and also the back up camera.  Then, it just pops out of Reverse with the shifter all the way forward.  So then the game begins.  Back and to Drive, Reverse.  This goes on 8 - 10 times. Very frustrating. Had it back to the dealer and they replaced some kind of computer, but it is now happing again. It is so bad, my wife will not drive the truck, she is afraid of being stuck somewhere.    Anyone else with this PIA problem?
