Hey so I had a Bose system in my truck. I ripped everything out initially and did aftermarket audio with a wavetech LOC and still hated the fixed sound. So I ended up replacing the head unit. I went with a kenwood dmx 1037s and absolutely love it. The only thing is you have to set your comfort features before you switch as you can’t really adjust after….such as mirror stuff or lights staying on. I wouldn’t go back. It’s a costly process though and you need a few harnesses. I’m probably 4K in audio alone.

Just for reference. My 2015 5.3 with a 6 speed is lifted on 37's and I went 4.56 gears front and back. Its perfect. I'm also tuned for premium with headers and full exhaust. I'm pretty certain if I had 35's I'd do 4.10s. My buddy who lowered his Silverado 5.3 and went with 22 inch rims and 32s or 33s did 4.10s and he loved it. 4.10s will have a bit more snap out of the hole but will rev a bit higher at highway speeds than 3.73s it all depends what you want. I can drive no problem at 70-80 mph. Gas mileage is a different story at those speeds though lol as my trucks a brick on the highway.

You'll absolutely love them. I have 37's and threw 4.56's in as soon as I could. I can spin the tires no problem.

If anyone needs pictures sent I can via e-mail. I have the 2016 headlights on my 2015 black all terrain. I haven't figured out the picture uploading process quite yet lol. Email is [email protected] Just send an email and I will reply with pics!

Watch the offset that's the only thing. I have a -44 mm offset set at 9 with a 1.5 inch body lift and I still had to trim the lower valance. Also, in reverse at full lock I rub the inner, lower part of the fender flare as well. I'm running 20x12s with 37x13.5r20 toyo mts. I may not rub if I didn't have the fender flares.

I run 37s on mine. I have a 7-9 mcgaughys set at 9 with an add a leaf and a zone 1.5 inch body lift. I had to trim the lower valence. It does rub just slightly on the fender flare on reverse at full lock. But this is with a -44mm offset 20x12 inch rim. I'm sure if you went with less of an offset it would clear easier as well as not having fender flares. Also they are 37x13.5 so the added width from the tires doesn't help either.

I'm Glad you posted this I am picking my truck up tomorrow with the same lift only set at 9 with an add a leaf and a 1.5 inch body lift. I'm guessing mine might be a tad stiffer than yours. I'm surprised that your rear end is 1 inch lower as they advertise completely level at 8 inches and 1 inch difference at 9 inches. Looks amazing though nice truck!

Just dropped my 2015 gmc sierra all terrain off to get lifted. I'm going with a 7-9 mcgaughys black ss lift set at 9 with an add-a-leaf as well as a 1.5 inch zone body lift. I also have a set of bushwacker fender flares and 4.56 yukon gears. For tires I am using 37x13.5r20 toyo open country m/ts and for rims I am using 20x12 fuel assaults with a -44mm offset. As well a cat back borla atak exhaust. I am beyond excited. Pictures will come when I pick it up!!!
