I too just bought a Z71 LT with 265/65/18, i put the GM level kit in it, but it still seems low with the running boards on it. I'm looking at bigger tires, but we seem kinda limited in sizes. What larger size tires has everyone seen on these 18" rims?

You think you limited.... Serria need a 6 inch lift AND trimming to do a 35....

You can do 37 with the same lift kit.

My stock size is 33", up until 6 inch kits that's as large as I can go.

(Can't trim due to the gunk they throw on the road and the uncoated frame)07ad908e8c1eaf4c444738d9198564af.jpg

Looks a bit nose high, I'm sure it isn't, just looks that way.

Love the look though. Was it a spacer in addition to the GM lift?

How did the ride quality change going from a Z71 to the Trail Boss suspension? Like in what ways is it different.

The kit did add more rake to mine. I never measured to see what leveling kit would be best for my rst. Here's a pic of it on level ground. Rides nice in my opinion but this is my first lifted truck. Everyone says the TB ranchos are junk...?b3ae270d475bc7285e85229a19b601d9.jpg

What I found is it really depends on what you're driven and what you've not driven for instance for me although I recognize that a linear spring is much more predictable I actually prefer a variable rate spring such as a dual rate or, in Chevy's history, a torsion bar.

a lot of people said the 2019 trucks are jiggly and this is true at 30 miles an hour I definitely felt a little jiggle even on a non Max tow truck but here in Alaska with a lot of random dips at highway speeds and Crest and double bumps, don't forget frost heaves. The ride is extraordinary well-controlled on the base 4X4.

in contrast my X31 is incredibly smooth at 30 miles an hour, no juggle whatsoever, however at 60 to 70 miles an hour over those same bumps the suspension bottoms out or overextends.

I also feel the need to point out that the 2019 AT4 and Trail Boss suspension is different then the 2020 version. The shocks are tuned differently to allow more medium to high speed trail running.
GM made this change directly in response to Media feedback that the back end was too Skippy on washboards with the 2019 model.

I suppose I should just go to a dealer and drive a Trail Boss model and I'll know since I commute on roads near the dealership what the actual difference is.

The front is a tad nose-low actually.  Yes, the level kit is just a preload spacer under the coilspring.  The ride to me is virtually the same as stock.  I'm happy with it.

I just got a RST too.   Did you have the dealership install?  Wanted to get a ballpark on dealer install cost...

Looks great! I would like this exact stance. Just debating on this kit or the Eibach pro truck kit. For your additional 1.5”, did you just use a spacer? Did you install the amp steps? I’m looking into getting those.

The 1.5" leveling kit is just a Rough Country spacer kit.  Yes, I installed the Amp steps myself - piece of cake.

z71 are junk....TB ranchos are the better ones

Anyone looking to purchase the GM 2" lift kit from Bill Cramer Chevrolet won't go wrong. I too was skeptical but called them with my VIN and they squared me away. Everything arrived just as they said it would, but faster. Even though they have the best prices in the country, it's a little more than the aftermarket kits. Remember that you're paying to make this kit a part of your truck backed by GM, just as if you bought it from the dealer that way. That was money in the bank for me. 

 

...just my 2 cents.

Superlift, BDS, and Zone all have policies that if their lift kit caused damage they cover it.

Nothing wrong with the GMPP kit.

But want to make sure people understand that installing a lift doesn't void any warranties.

The damage would have to be SOLELY (i.e directly) caused by the lift, and GM would have to PROVE it. They don't get to just say it isn't covered, they must prove it.

On the rare situation where that happens that's where Superlift, BDS, and Zone would step in. I believe Rough Country has something similar.

This looks great.  The GM 2' lift kit re-calibrates the electronics/camera for LTZ safety features, and I'm not sure how things work with the additional front level....?

    • I never understood the hate for the column shifter. The console shifter just gets in the way, takes up prime cargo space and in my wife's Jeep, the dog constantly bumps the console shifter into neutral!    Best choice ever to just make it a column shifter across the lineup and be done with it.    (Bonus: Makes swapping from a 5 seater to a six seater far easier)
    • I had an 88 K1500 with a 5.7 that had those symptoms, I know totally different, it ended up being the ECM. Once you get the fuel system fixed if it still runs lousy you may want to investigate that. it didn't set any codes, stalled ,ran rough at times etc
    • Congratulations Isttype, on your gmc. Really like my 2024 2500hd sle doublecab now with 85,500 miles.  I checked the oil today at 4800 miles since last oil change and barely reading on the stick.  I don't care if GM says it's Acceptable adding a quart every 2000 miles because that is 100% BS, It is not a 1966 Harley Shovelhead! Sounds like it's setting up a future failure like I had with my 1500 6.2l. Other than oil consumption problems, I really like the 6.6l gas and 10 speed is really nice.  Towed a light 4000 pound trailer last week and averaged 14 mpg.  I was pretty impressive that a 7300 pound gas truck did 14mpg towing, Later-
    • Long Term Cold Cycle Limited Testing   Back to the 1990's and XOM's million mile test. Since then there have been others and there will be more. Schaeffer's, AMSOIL to name two. Of these Schaeffer's is the stand alone which I will explain in a bit later.    http://papers.sae.org/600190/:   http://papers.sae.org/850215/:   Up to 75% of  engine wear occurs on cold starts. These two links (above) provide the technical reasons for engine wear. In a nut shell, and by a large margin, cylinder wear is what takes out most motors and even with a pre-oiling system that part of the engine is dry enough on cold starts and cold warm up to pierce Stribeck.   So when you put a motor, or a car, on a dyno for a million miles stopping only for oil changes, (yes fuel is uninterrupted) or break down maintenance, you are depriving the test of the most important part of it's wear cycle. Yes a million is then a pretty easy walk even for a mineral oil under those conditions.    How about cleanliness during the long test cycles? Same thing. Varnishes that stick rings and insulate parts are laid down by repetitive 'heat cycles'. It's the cool down the precipitates the varnishes. These long runs also hinder acidic attack caused by cold start richness and less than optimal cold start ring sealing. They hinder water formation and enhance breathing of the crankcase; the petri dish of acid formation, the first step in sludge formation, amalgamation and precipitation. These motors are also monitored and controlled for water and oil temperatures to within the "normal operating range".      https://www.swri.org/sites/default/files/sequence-iiih-test.pdf Note the test sequence in some boutique oils literature for testing, API IIIH, is not the standard used for the ILSAC G7 testing. Does that mean it is irrelevant? No, not as used. As used as a 'visual guide' it makes it's point. The G7 weighted piston deposit minimum is lower.      Back to Schaeffer's. That was a cyclical test of an engine in fleet service and not a dyno mule and if you saw the video it was not mirror clean but wear was low.    There are oils like BioSyn and other 'Renewable" source oils that taught cleanliness and have proven themselves in fleet testing. Havoline an other example.    The newest ILSAC G-7 test prioritize cleanliness, LSPI mitigation and fuel economy OVER WEAR. In comparison Porsche C30 Specification Verses ILSAC G-7 Specification below:      Some will balk that this graph isn't apples to apples and I will challenge that in that this graph represent the SPECIFICATION and not the any One Oil Performance.   It is absolutely possible to minimize wear, maximize cleanliness and mitigate LSPI etc., It just isn't cheap and currently I see none that are not walking toward profit over performance.
