Can't Lift A Denali?

Another lesson:

Went to the GMC web site.

No mention of autotrac for the Denali! It's there on the various 1500 models, but not a whisper of it on the Denali site! Apparently since the AWD transfer case is always in 4wd, there is no autotrac feature for the D.

 

So, if Stabilitrac has control of the brakes to pulse them as necessary to control slides, what is the electric strut called? Also a part of stabilitrac???

 

When I talked to the engineer at Fabtech and BDS, they said Autotrac was the big bad wolf as far as making this kit work/not work.

 

Since we have a member here who has taken the bold step of actually bolting the BDS kit on, we know it fits. And we know that it only takes a dual cardan driveshaft to get rid of vibration. That means for all four people in the US of A who are going to lift a Denali, that it is possible, and indeed feasible!

 

Thanks for the emails, PM's, and calls which has made this thread possible!

Not an expert here, but I think the problem with the lift is the autoride, not autotrac. Autoride involves electronically controlled shocks and struts which are a problem that would have to be dealt with on a lift. You are correct that your Denali would not have autotrac.

Glad you got it alllll figured out. Got any pics of that 01 Tundra?

 

 

Here's a couple...

 

Now you know why I can't stand the low rider look!

Thanks, I like it too

 

However...

 

I have sort of moved from the radical crawling scene to the "more comfortable" off roading scene. (Witness the H2) Now I have the Denali for everyday driving which means the H2 can get a set of aggressive tires and fill my need for off roading.

 

All that translates to, the Tunrra no longer has a use in my household. Worse yet, my 16 yr old daughter wants to drive it (Tundra) very badly. Knowing she will shortly roll it over and possibly injure her, the wife and I decided he Tundra is going to a new home. We Ebayed it but it failed to meet the 15K minimum I put on it, so it is still at home, but we will eventually sell it, and live with the H2, the Denali, and the Suburban.

OK guys...I haven't been to the site in some time, but got a PM email from Don (flyin6) about my lifted 08 Denali nd decided to get back on this Forum to see what was happening.

 

Had I read all of this confusion / doubt about lifting the new Denali...I think I would have been scared out of my mind to do / try it! But, luckily when I decided to do it, there wasn't all this doubt out there! :cheers:

 

I literally stopped at a local mod shop and told him I wanted to put a 6" lift, wheels and tires on my 08 AWD Denali. He looked it over, caleld BDS and had a kit for it 3 days later. Installed it, I took it home and had a few issues with it and took it back in to rememdy. The biggest issue I had was with a howling / grinding noise in the front-end when I let off the acceleration (ie. cruise set at 80mph, tap the brake and it would growl until I got back on the gaes). After visitng with BDS tech, we determined that it was excess chatter in the front driveshaft due to modified driveline angle from lift and could / should be corrected with fabrication / installation of a new dual cardan setup.

 

So, I had a dual cardan driveshaft made, installed and SHAZAAM! Problem solved. No vibrations, no growling / grinding / howling...just a bad-ass lifted truck! It is slightly rougher riding...but then again...I didn't expect it to ride like a Cadillac with those mods! I recently took it on an 800 mile trip with 3 of my buddies and they were AMAZED at how nice it rode, how quiet it was and the 19 - 21 mpg average it got on the trip.

 

I have lost a little power by adding the larger tires (way heavier than stock setup)...but it still goes like a raped-ape when I need it to. With over 400hp stock, there is plenty of power when needed. I plan on doing a tune and programmer which will help get soem of that "stock" power back.

 

Sorry, I got a little sidetracked from the subject at hand here. As far as these lift comapnies saying it can't be done (lifting an AWD Denali)...then, how the hell is mine functioning with virtually NO issues!? I was in contact with a tech at BDS a dozen times in regards to my project and he NEVER ONCE told me I shouldn't / couldn't do it!? So, I guess I have to keep my fingers crossed that I didn't do something stupid and screw up a $50,000 truck by doing it huh!

 

Here's a little "proof" that the BDS setup can / is installed on an 08 Denali AWD:

Thanks for chiming in here! That was all good to hear. We are basically expanding the database here in doing things before untried. That will pave the road for others to follow along more easily.

I'm glad you chimed in. I knew I had seen at least one or two lifted SD's on here. I just couldn't remember who had done it. Thanks for the input!

      Transmission Temperature Hitting 220s

      By Grumpy Bear · Posted

      After I wrote that reply I went for a ride. 85 F out. So trans started at 85 F and it shifted the same as it did an hour latter at 168 F. I've never actually recorded the to cold to shift point but it is under 32 F before they start hanging on to a lower gear or leaving the converter unlocked. Both intended to heat fluid.    Yes, brake or bake. Absolutely.      Your welcome. True research ended decades ago. Field trials are still in play.    There is a thing called oxidation onset temperature. This is the heat related oxidation not the O2 exposure kind. For mineral oil that starts at 140 F. So what happens after 140 F? Each 20 F cuts fluid life in half! Does using a Full Synthetic improve that? Yes! By how much? Depends on the base oil type and a few other factors. But enough to notice. Some esters are even higher. There are even synergies between types the will raise it higher than any one component is alone.    Then there is "Hindered" oils. Antioxidant additives. Hindered Polyol Esters can sit at 500 F for years in a turbine.   When a blender brags his oil will 'take 500 F" in service he doesn't specify for how long. Water will dance on a 500 F hot plate for several seconds. @newdude put up a chart showing the relationship between fluid temperature and it's life in an automatic transmission. Here's a version of that chart for Group III based oils. These temperatures are those in the pan as observed as 'normal'. that is you drive as you do for as long as you do under what load you ask of it and whatever that temperature is this graph applies to. Flash temperatures of a few minutes isn't what his means.    Note that fluids held at a constant 240 F have a service life of only 20K miles. 220 F explains the factory exchange limit, eh? My equipment I keep under 180 F and I'm good if the cooler will hold it as low as 140 F. But that's me.

      Actual Full Screen CarPlay on Refreshed Silverado/Sierras.

      By Greg3160 · Posted

      Im in the same boat. Carlink adapter comes tomorrow and dev account is in process. Would you he able to send the new instructions my way also? Question, do you have to change code and republish app everytime developer updates? Thanks for your assistance, truly the only thing i cant stand about my truck is the carplay limitation

      Weight limit in bed

      By rav3 · Posted

      And Google AI says......... Yes, your truck can technically handle it, but you will be right at or near its maximum limit. A 2016 Chevrolet Silverado 1500 High Country with a 6.5-foot bed has a maximum payload capacity of approximately 1,770 pounds.Weight RealitiesLoad weight: Half a cord of dry hardwood weighs roughly 1,100 to 1,500 pounds depending on the wood type (like oak or hickory).Payload limit: Payload includes the weight of the wood, you, any passengers, and a full tank of gas.The math: If you weigh 200 pounds and have a full tank of gas, a 1,500-pound load of wood puts you right at that 1,770-pound ceiling.Safety TipsCheck the yellow and white sticker on your driver-side door jamb for your truck's exact payload number, as high-end luxury trims with extra features have slightly lower capacities than basic trucks.Expect the rear end to sag noticeably.Drive carefully, avoid sudden turns or stops, and keep speeds low if you have to travel a distance.
