FYI 6.2,

Everything you need to do your lift is on major backorder.

McGaughys is a month to six weeks out. You need UCA'S to go 9" also. Shop around. Cognito, Kryptonite are top shelf. Bolt on easily replaceable ball joints. McGaughys have pressed in ball joints.

Even tires are hard to get.

A lot of wheels come from China so guess what? I suggest you take a look at Custom Offsets www. I ordered everything from them except the UCA'S. I went with Kryptonite from Alligator Performance.

Plan on getting your lift done in November.

****** I haven’t got it priced yet but hear from 1500$ to 2500$ price range over here in DFW area

Everything he's says is true.
However I'm running a 2018 Crew cab standard bed on a McGaughys set at 9 on 37's with a 5.3 6spd. 3.42 gear. Superchips Flashpaq F5 tuner. 92 octane tune. Borla catback exhaust.
It's not as bad as everyone says. It gets down the road just fine. 15-16 mpg all day long on regular two lane 55-60 mph hwys. I tow a 3000 lb 6x12 a lot too. No prob. Just give it more gas. 
Even with your 3.23 gears your 6.2 should have enough balls to get you down the road on 37's no problem. 
 
 

Just having enough balls to move you down the road will not be enough, having a 6.2 with just a 4.5”-5” lift and larger heavier 33.5” tires does impact acceleration, braking and maneuverability, couldn’t imagine what a 7” with 35”-37” would do without re-gearing and tuning, it’s definitely going to be very noticeable and obviously somewhat dangerous as acceleration and definitely braking will play a very large roll in daily driving, especially normal/daily maneuverability.

Accessing older parking garages was my #1 reason for my lift height which will definitely play a big roll as your only vehicle. Towing, which is doable will require re-gearing in order to satisfy the massive power loss with that much tire weight.

There are plenty of people with larger lifts that don’t care that if all these are reduced, they just want the look. I tuned my 6.2 and noticed a substantial difference in acceleration and mpg’s.

IMHO, Anything over 6” will definitely require tuning and re-gearing, possible leaf spring package and performance shocks, upgraded braking. Custom rear air bags come to my mind.
