There was a guy on the forum a couple months ago completely freaking out and didn’t know his track width would change so drastically, he was so very upset and even posted pictures on his driveway. All in all, you get what you pay for and most of all “DO YOUR HOMEWORK!”

I researched all the liftkits out there and the Gen 2 kit from Fabtech was the only one that did not widen the track width. Also I was limited due to the magnaride system on the Denali. No issues with the system so far just like to have heavy duty shocks & struts to handle off-road & bigger tires. The truck does ride nice! Anyone heard of AMP tires?

I almost bought the Denali but didn’t want the Magnetic ride so I ordered a loaded out SLT. To many issues with Magnetic ride breaking down and Magnetic Ride warranty voided if lifted. All in all, the dealership techs were very impressed in my CST setup and Service Manager now wants my full setup on his 18. That should say a lot emoji6.png

I bought my 2015 used at a killer price. I wanted the All terrain edition but hard to find. No regrets so far. Denali is a beast with the 6.2!

CST doesn’t widen track either allowing you to use your stock wheels as well as stock turning radius. CST is a custom built made in the USA, everything built in house with the highest quality material available, second to none. Their welding process is phenomenal and even use gussets to reinforce their lifts not found in other brands. I even physically compared the CST parts to ProComp, BDS, FabTech, Zone and a couple others minutes before install started and was amazed at the high quality and far superior craftsmanship compared to all the rest. You should check them out, you’ll be just as much impressed.

Now ya talking, which tune did you use? I haven’t done mine yet. Installed a cold air intake and Gibson exhaust & I am happy with that combo. Ready to tune now or after I install the 35’s

I’m not sure if CST makes a kit for the Denali?

Hey mpg is 22 mpg with the factory 20inch tires. I will be adding 35’s soon on stock 20 inch Denali wheels

Good question [emoji848] but I’m sure there is some sort of bypass just for the rods of the Magnetic ride. I’d call them end of the week

Because of my factory warranty, I wanted to stick with something I can reset before going back to the dealership for warranty work. SuperChips F5 does everything and super easy to use. https://superchips.com/shop/v/gmc/sierra-1500/2018/6-2l-8-speed/
This is for the 6.2 8speed transmission but they have one for the 6 speed too which will allow you to program the 6 speed not the 8 speed.

If you are getting 22mpg with a 6.2... you be pampering it.. 35 in. tires will take a little more throttle.
I had a 6.2 in my 2011 with 33 in. tires.. 15mpg and premium fuel were the only bads.

Yeah 22mpg—jeez. I do 16mpg period with 6”, 35’s, 4.10 gears, and 93 octane tuned on 5.3L.

Yes I watch the fuel economy while I drive, get the 4 cylinder mode to kick in premium fuel with no ethanol isn’t cheap. I know the 35’s will cut into the fuel economy but that what I work for to enjoy my toys

I have the 8 speed trans. How is the horse power after the tune? Can you set it to compensate for the 35’s?

    • So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.
    • My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.
    • Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?
    • I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions. 
    • I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
