I tossed mine in the trash when I upgraded. I would feel bad trying to sell someone such a crap product.

Been very happy with the GM 2 inch lift on my SLT. First pic is before lift.

I'm opposite all this..lol.  I would not pay 1200 bucks for white shitty ranchos...no offense to anyone.  For a lil more you can get coilovers up front and a block kit with shocks for the rear. Plus i

What is the electronic steering calibration GM says we need? 

Does it vary on tire size?

Just what it says, it calibrates the electronic power steering to compensate for the higher ride height.  It is not tire-specific.  They also perform a calibration on the forward-facing camera.

For everyone who got a lift which did not include a calibration, how do you find the steering to be affected?

Why would you not get the calibrations?  They are included in the cost of the kit.

Thank you for these before/after photos.  It looks great IMO.  I am looking to do the same on my Elevation.  I got a response from one local dealer who says it'll be $900 to install...does that seem like a fair price?

Thank you! Is that price with parts or just the install portion? If just the install then you can definitely do better.

Yes, that was the dealer install option on the GMC Accessories website. I’m going to call a couple shops to see if they can do better. Thanks for the reply!

I used a bilstein 2.5 strut in the front and a 0-4 inch rough country and 2" block in the back and got a sold 2.25 inches all around.It is a noticeable difference in ride quality especially on the bigger bumps. I was looking at the southern cal coil over setups which are nice but they are not made for northern climate and just won't hold up to road salt & mud. Not only that but they require regular service which in Canada costs more than the 1 time cost on the bilsteins. To all those going higher than 2 -21/2" good luck as every mechanic I have talked to says the long term costs will get you ie ball joints & cv angles and drive shaft angles (unless you start putting in drop brackets). All in I was just over a grand Canadian and say it was a great buy. The other thing to watch for on a taller lift is the fuel lines on the 3.0 duramax as it's not good for them. Just my .02$

I've never had an independent front 4x4, so I never gave a lot of thought to the way steering is affected through travel  at a range out side design. 

I haven't seen a lot of requirement for recalibration on the higher lifts. I would think this is because the control arms in higher lift kits correct the angle.  Is it angle or added torque from the longer "lever arm" that it corrects for? 

If its angle, then how does the electric steering do under more extreme articulation? 

What does the calibration correct? Just the baseline angle sensors so the comp doesn't read turning input that doesn't exist?

Why not use a dropped pittman and reinforced or braced box?

Just had the 2" factory lift installed on my 20 Sierra Elevation, part number 84993582. Got the kit for $980 on sale from GM Partsexperts and got it installed for $513 + tax ($408 for the install and $105 for the wheel alignment) at my local GM dealer. For some reason they were cheap compared to other dealers I called who were quoting between $800 and $750. They did all the calibration and computer updates. The only thing I wish they included was the headlight adjustment but that's easy enough to do myself.

 

I love it, looks just like an AT4 from the outside, high enough to look more aggressive but not outrageous. Ride is comfortable, a little stiffer but may just need to settle.  Factory warranty is still intact and I kept the old parts JUST in case I want it back to factory.

Those with a stock AT4. What are y’all’s stock wheel well height stock, and/or what are your  wheel well heights with your leveling kit? Front and rears, please. 

I forgot to measure before installing Icon leveling kit.

 

I have an AT4.  I installed Icon leveling kit, UCA’s and rear Icon shocks.

After 1000 mile break-in, 4 Wheel Parts did final adjustment, after “settling”.

 

My rear height is 40”, and my front height is 41” (left) and 40 3/4 (right).

It seems my front right tire is already getting excess wear on outer edge of tire.

Also, truck is NOT happy driving in AWD upon acceleration since the lift.

 

installed at 4 wheel Parts.

Sounds like you may need an alignment.  Also, the owners manual tells you the AWB setting shouldn't be used full time.  It's meant for when the road condition could be slippery are loose.

I think he is referring to those who got an aftermarket lift where no steering "calibration" is offered.

I just had an alignment (my 2nd) after the 1000 mile break-in service of the Icon suspension leveling kit install. I noticed wear on the tire after the 2nd alignment….and only 200 miles of driving.

i think they raised the front 4”+.  I think it creates bad angles and even a perfect alignment won’t fix that.

Going back to 4 wheel parts to lower the front an inch, which will make my truck level.

 

And thank you for the info on the AWD mode. I did not see that.  Thank you much!!!!!!

Your welcome.  Not using it full time will increase mpg and decrease wear on drivetrain.

      This video may not be the exact content for the joke thread but its a lot of laughs so here it is, I've only watched a portion of it so far but if anyone is looking for some light hearted good soap box driving action, its here. As a note in the upper left of the screen it shows the number out of 100 to refer back to any particular vehicle for comment !.    https://www.facebook.com/reel/1351928276956715

      2023 DRW Wheel Liners

      Did have to make 1 modification because of the WeatherTech rear mud flaps and that was needing 3 longer screws than what came with the install package. 😄

      Picked up the liners yesterday. Installed passenger side WITHOUT any modifications. All mounting holes lined up perfectly. Rain is interfering today with drivers side. Very Happy! Will add pics when finished

      OCI, not when but why?

      As a matter of amusement I’ll leave this conversation with this. Do you beat the government average fuel estimate? Statistics are a guide to me. Not a rule. Someone once said I have to have the last word. If true and possible may be. I’ll blame that on working in a family business.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That is a fair point, and I agree that trying to log “everything in the truck” would be the wrong direction.   There are a lot of modules and a lot of traffic. If the product became a full-truck datalogger, the amount of data would get huge very quickly, and most owners would never use it.   I think the first useful version would need to be narrow: - powertrain-side event evidence - selected high-value parameters - communication / voltage / reset events - pre/post event window - short report first, raw log only as backup   One distinction I should make is between active OBD/PID polling and passive bus capture. If you are polling PIDs through OBD, then yes: the more parameters you request, the lower the effective sample rate becomes, and you are adding diagnostic traffic to a vehicle that is already busy running itself. With passive CAN capture, the recorder is not asking all the modules for data. It is listening to traffic that is already on the bus. So it does not consume vehicle bus bandwidth in the same way that a scan tool polling hundreds of PIDs would. But your point still applies in a different way.   Even if passive capture does not add bus traffic, the recorder still has limits: - processing rate - storage rate - timestamp accuracy - decoder workload - event filtering - report size - user attention span   So the answer cannot be “log everything and let the user figure it out.” The product would need to store enough raw evidence to be useful, but only decode, graph, and present the important parts around the event.   A practical report should probably show: - what triggered the capture - how much pre/post data was preserved - which selected parameters changed - how those values compared to baseline - whether the same pattern happened before - whether any voltage, reset, bus-off, lost-message, or communication fault occurred - selected graphs around the event - raw data only as supporting evidence   So I agree with you. More data is not automatically better. The real product is the reduction from raw data into a useful event report.
