I'm new here and just tried to search for this topic, but didn't find anything so here goes.  I just bought a 2021 High Country 1500 4wd with the 3.0 Duramax and Adaptive Ride control.  I want to lower it 2" all around and the kits I've seen so far say will not fit with adaptive ride.  Can anyone explain the issues of lowering a truck with ARC and what it might take to lower one?  I had a 2019 High Country 6.2 4wd and lowered it as soon as I got it and really liked the look. A pic of the 2019 is below.  1927088371_2019HC.thumb.jpg.c96ddf9dd3c51ef9e6f9503957233d3d.jpg

 

Thanks

In in case anyone has any information!

 

I think the issue is just the sensors, it actually should be pretty easy to resolve, but waiting on companies to actually get it done. if you just lower the truck with ARC the ride height sensors will basically read that as the suspension is always compressed and will respond by stiffening the stocks ruining the ride, might cause premature wear also, not really sure. also possibly throw error codes as the truck might interpret that as a sensor failure. there is at least one kit out there for raising an ARC truck, to solve the arc problem all it does is add a bracket which moves the sensor attachment point to compensate for the new ride height so the sensors still correctly detect the truck's suspension as its resting position when that's actually the case. lowering should be solvable the same way, you just need to adjust the attachment point for the sensor. but as far as I know no such kit exists yet for lowering. I would like to lower my Denali at some point.

Don’t have ARC, but curious what parts you used to lower it.

I used BelTech drop spindles on the front and shackles on the rear.  I think they see both as a kit now, but I got them separately on Ebay.  Easy install with 22" wheels.  Some smaller wheels require a thinner nut on the lower ball joint and you may need to trim the end of the ball joint stud for wheel clearance.  The thinner nut is supplied with the spindles.

I wondered about changing the location of the sensors.  When I can get it up on a lift, I'll look into it.

Thanks for the info on the lift kit!  It makes sense then that a similar fix would work for lowering it.

Your previous truck looks perfect - love the stance. Have been researching this as well. Exactly what I am looking to do w/ my 2021. I just sent switch suspension this question. Will update if/when I hear back from them. Otherwise I will talk w/ my local guy who has dropped a lot of magnaride trucks. I assume it is a fairly similar setup as kodiakdenali said.

I inquired about the Belltech 2/2 kit and this was their response:

"The 2/2 will work with adaptive ride. The Denali that is pictured with that kit is a friend of ours that we did the install on."

very interesting..and a great look too. so I guess this is 2" front and rear so its lowered but retains the rake? I could probably live with that. which kit exactly is this? I'd enjoy hearing from anyone else who has this done how it is, good quality? I wonder what the cost is to install something like this...if I could get my truck lowered a bit id get the look I want and also be able to remove the power steps which I don't really care for.

Interesting that they said that it would work with Adaptive ride when all the ads I've seen says it won't, BUT, the spindles do not change the relationship of the upper control arm to the frame on the front, so it should not throw codes and be fine.  As for the back, the shackles will change the position of the rear axle in relation to the frame, so I think there may be a need to change the length of the links or re-calibrate the control module.  Thoughts?

I just lowered my 2023 gmc sierra ultimate denali with arc and the ride is very stiff

i used the rough country 1.5-2" drop shackle. Truck looks good leveled but ride sucks, and the drivetrain vibrates at 25-30mph. Going back to stock shackle.

    • There would be one way of determining the quality of the factory oil although probably more than a typical oil lab test, and that would be to draw out some oil from a new truck and send a sample to a lab that could do a more elaborate test of the oil. The issue with too little oil in the diff may not be the lack of lubrication of the diff bearings and gears themselves ( although a lack of oil volume for cooling ) but the wheel bearings because at some point the oil would be too low to properly get onto the spinning axle or fed along the axle tube. That was the claim by the local dealer from a couple of trucks in recent years that had the wheel bearings fail and they figured from lack of sufficient oil due to a severe underfilled diff and some of the bearing material made its way to the diff and it got damaged as well so the axle housings were just replaced on warranty. But your right that if the diff is over filled by whatever margin that it causes more churning of the oil than is desirable and that is no good either and can cause a pinion seal to leak. Also old oil I believe can tend to loose some of its properties like antifoaming and another good reason to change the diff oil every so often. 
    • I would be surprised if the diff's were not filled (with the cheapest gear lube) at the axle factory before being shipped to GM.  If you ever watched them building trucks they install the axles and all suspension parts with the frame upside down and then turn it over before its time to install the engine.     Too much gear lube in a axle can be worse than not enough especially with a lower quality GL where is get whipped up with entrained air (foam)  weakening its ability to lubricate.        
    • This is the 6.6 gasser section of the forum, you should either delete or modify your previous post as it is misleading for anyone looking for factual information on their 6.6 gas engine.
    • Well....I've done my first intake gasket. Probably wrong, but...we'll see?   Ultra black on the china walls and 1/4" up onto the sides of the intake gaskets. Permatex High Tack (couldn't find Gaskachinch) on the head side of the intake gasket. I read wrong and it says you're supposed to put it on the mating surface of the head, not the gasket. Hoping it's like a PB&J sandwich where it doesn't matter what side the PB goes on so long as there's jelly. That crap is messy/sticky and I got a dab or two on the intake port openings, tried to wipe it off. Hopefully it won't be a big deal and will only aid in sealing.   Per instructions I left the intake (top side) of the gasket dry except for a light smear of RTV around the coolant ports. Wiggling the intake in there was a bear but I had help to free me of surrounding wiring/stuff but I was basically able to set it straight down lined up with the bolt holes.   I did not think to wait until the RTV skinned over but there probably was 5-10 minutes while it sat before installing the intake.   Bolts finger tight first. Then, followed the Chilton's manual pattern to snug them to 15 lb-ft.   Waited a little over an hour, and then did the final torque in sequence again to 35 lb-ft.   Yesterday I replaced the fuel pressure regulator and got my new "nut and bolt kit" (fuel lines) installed. Damn GM used security torx on the spider, which I don't have, so I got scammed at the local HW store for an off-brand security Torx bit set.   The new driver's door mirror arrived yesterday, so, there's a chance this thing could be running and road legal tomorrow? I don't want to get my hopes up.   This will be my first time stabbing a distributor, too. Although, lucky me, someone else marked the old distributor for removal previously, I did see that. (Someone's been here before!!). Engine is still at TDC so it *should* be just a matter of transferring the mark to the new dizzy and rotating it into place.
    • He has his dad’s newer truck he’s put away. He has several old cars he rotates between him and his family. I’ve seen a restored square body and a SS Chevy truck he’s sometimes drives. He did raffle off a new suburban recently. As much as he is watched if he drove new stuff as a rule we’d know it. It would be fine by me. I don’t care what people prefer. I got one more new one in me. I’d rather my wife get one. I can’t get her out of the Genesis. Don’t tell anyone. I want her to get an electric truck. I want to put a generator in the back. Just because. She hasn’t bit yet.
