mayfieldjeff · July 1, 2020

Just put a deposit down for a 2020 1500 AT4, all black.

here are the things i am doing to it. what else have you guys done?

truck is coming with the performance exhaust upgrade.

putting a 2" level kit

taking off the stock wheels and tires and going with a GM all black wheel 20" and 285/65/r20 Nitto Ridge Grappler

taking off stock step bars and putting the amp research power steps

adding hard folding tonneau cover

replacing chrome exhaust tips with black tips

i plan on selling the full set of stock wheels and tires and the bars...

i am thinking about getting the kicker subwoofer added too.

can't think of anything else but i may be.

Very cool I can’t wait to see what you do. I bought a black 2020 AT4 5.3L a few months ago. I love it! All I’ve done is had the dealer install the REV hard tonneau cover. I’ve got an organizer for the giant center console coming and I’d also like to get some vent visors.

Performance intake air filter setup. Brembo will go nice with the 20" wheels

Did your's have the stock 20's or stock 18's? If it was the stock 20's that look like this I may buy them from you.

Do you like your S-Type? Trying to decide if I should go for it or go with the ATAK.

Installed my Bakflip MX4 today, anyone had them propped up all the way against the rear window using the gimpy looking prop rods down the highway? They do not look secure enough to stay up the way the promotional instruction videos say

Love it. It really depends on individual taste but I think it’s about perfect and I get many compliments on it and people asking “what exhaust is that? It sounds so sweet!” It’s actually louder than I expected on cold start but then quiets down quickly and I have virtually no drone. Generally quiet cruising unless climbing a steady grade, then I’ll sometimes hear it.

I’ve used them several times and not had any issues.

It has occurred to me to ask, what cab configuration do you have? Short box? I am suspecting the different box length would result in different mounting position for the prop rod to the plastic rail it sits in

Crew cab, short bed.

I have 2019 AT4 Carbon Pro 6.2L - 10 speed

Done the following so far:

AT4 badges replaced with black ones, from 2020 Carbon Pro

Exhaust tips replaced with black ones

Ready Lift SST 2" level kit and upper control arms

18 x 9" - 18mm Offset Method NV wheels

275/65/18 Wranger Duratracs (stock tires)

GM Performance Package (came with cat back exhaust - added air box and tune)

Came with kicker speakers in tailgate

Very happy with truck.

Looking to upgrade shocks and may do BDS 2.5" lift with Fox 2.5" coilovers and Fox 2.0's in rear to upgrade suspension from the RL SST/stock Rancho shocks - that looks nice and rides decent on road, but has limited offroad potential - to something that performs well on an off road. Add Deaver rear spring pack at the same time and finish it off with 285 or 295 BFG KO2's .

Few photos - from stock to current

yes it is those 20". i am planning selling them along with the stock tires. they will have zero miles on them. truck is still in transit so once they get it they will take these off and put my new ones on immediately.
