2024 GMC Sierra Pro upgrades

gmcdawg · March 29

So, without endless searching of threads that may or may not be helpful - can I get some folks help me with some specific mods I can do to upgrade my 24 GMC Sierra 1500 Pro to do the following?

Specifically, interested in what harness plugs are there for any interior upgrades like dimming rear view mirror/tow mirrors, etc. May do the aftermarket radio upgrade eventually with the big screen setup, not sure if there are others that are common.

Searching is your FRIEND. Don't be lazy. LOTS of this stuff has been gone over now since this gen launched for 2019 and refreshed for 2022.5.

The biggest hurdle is the platform. Harness Dr. for example makes a bunch of stuff to upgrade but only supports the 2019-2022 Global A trucks. 2022.5-current are Global B. You can check Gen5diy as well, they might have some stuff.

Mirrors, your only option would be Boost Auto. GM stopped after the 2019-2022 Global A years supporting factory tow mirrors.

Boost Auto | Quality Aftermarket Accessories for Trucks & SUVs

White Audio and Media for factory upgrades to low trims:

T1 GM Pickups (2022.5-2026) and Full-Size SUVs (2021-2024) (Global B)

As for lift. If you have the Mono Composite Leaf springs out back, you MUST convert to steel springs when lifting. Mono spring is not supported by anyone for doing lifts, including GM.

The Trail Boss/AT4 kit is nice but $$$, especially if you need the leaves. But it does get you the CV axles for the front which are a must when lifting these. If you don't like Ranchos, then skip the GM lift as it comes with Ranchos.

You will need to change upper control arms for ALL leveling kits, no matter what the manufacturer of the kit states. The stock arms WILL fail if you do not. Proper lift kits might not as they keep the angles happy. Leveling kits do not.

If you want a great ride and not compromise geometry...stock IMO, and maybe change shocks.

End of the day? All of this stuff was one search away. Also...sometimes its worth the extra $20-40/month payment, or same payment but a year or two older to just get the higher equipped truck and not tally up thousands trying to dress up a WT/Pro.

There isn’t much you can do with newer vehicles by design. My brothers Escalade just came off warranty. Even something as simple as oil changes can be challenging. He took it to a Valvoline quick lube instead of the dealership. They wouldn’t touch any newer than a 2019 6.2s. And use anything other than the recommended oil weight. 0-20 only not 5-30 like he wanted. He ended up doing it himself.
