'21 3.0L Duramax LT with diesel off road package (3.73 gear ratio)

2.5" leveling kit

35x12.5r17 Toyo AT3's

17x8.5 Method MR703 with 0mm offset 

(Cognito standard upper control arms are on their way - don't trust the stock ones)

I didn't have to cut anything to make them fit, just removed some parts and ziptied some carpet back.

Just got this last Thursday the 18th.  I traded in a '18 Sierra 5.3 Double Cab for a 6.2L Crew Cab.  I have a 34' camper that I pull and this should offer a bit more grunt.  Air Bags were the only mod for towing w/the 5.3.  Only thing I've done to this thus far is a spray-in (negotiated at sale) and removed the bedside 4x4 decals.

Well, did some more upgrades to the Work Truck package interior - this time to the dash.  I was tired of the (to me) boring black surrounds and plain gunmetal radio surround.  Upgraded to a few leather bits, chrome surrounds, and silver/chrome radio surround.  Enjoy!

Here’s my 21 3.0 Duramax High Country, Sally.  So far I’ve done: 2.5” front/1.5” rear Suspension Maxx level kit, Sumo Springs bump stops, S&B air intake, Chevy accessories hard tonneau cover, Sylvania LED reverse and tag light bulbs, 20% ceramic tint, and had the truck ceramic coated. Bought on July 3rd. Love her so far. Average 25 mpg on the highway at 10 over the posted limit and rides like a dream.
