Previously, there were a ton of resources you could download to stream newer DLC content into your FiveM servers, however this falls under piracy and leads to more issues than needed.
Slapping newer DLC content into a stream folder is blocked and won’t work.
There is a much easier way to have your FiveM server on a higher DLC level, however for whatever reason, people would rather roll their eyes when you ask them how to do it, and I haven’t exactlty seen much documented on it, at least, in a way that even a simpleton would understand.
Benefits Of Enforcing Gamebuild:
- Newer Vehicles
- Newer Clothing
- Newer Props
- Can request newer IPLs
- More variety for your player base
- More RP scenarios and possibilities
- More animations, emotes and scenarios can work with your scripts, such as DpEmotes
- More ped models to use / replace
and much more
Downfall Of Enforcing Gamebuilds 
:
After enforcing to a higher gamebuild, you may find your ymaps look different, or the roads may be invisible/blurry. Try using codewalker and setting the DLC to the same as your server and update the ymaps/ytyp’s.
You may also run into a case of constant crashes to the desktop when trying to load into the server; A common culprit to this issue seems to point to addon clothing, EUP or possibly add-on peds.
These issues may appear as the following:
-
b1604:
oven-happy-sad|| GTA5.exe!sub_1406B14FC (0xf) -
b2189:
earth-august-saturn|| FiveM_b2189_GTAProcess.exe!sub_1406D21B0 (0xf) -
b2372:
yellow-stairway-december|| FiveM_b2372_GTAProcess.exe!sub_14070E7A8 (0xf)
While you will be receiving errors in the console similar to:
InvokeNative: execution failed: Error executing native 0x00a1cadd00108836 at address 0x1407a0b54.
SCRIPT ERROR: Execution of native 00a1cadd00108836 in script host failed: Error executing native 0x00a1cadd00108836 at address 0x1407a0b54.

ASI Client Plugins 
.asi plugins now have to explicitly say they support newer gamebuilds.
Check out this forum post to get your ASI files working on FiveM if they are not already working, however use at your own caution as this is not an official solution.

HOW TO CHANGE GAMEBUILD ON FIVEM:
ENFORCING GAMEBUILD IN WINDOWS 
:
on windows, open your run.bat file with Notepad++ (Download Notepad++ here: Downloads | Notepad++) or any text editor besides Window’s default notepad.
Add the following: +set sv_enforceGameBuild XXXX - Enter the build number in place of the X’s or simply use the aliases.
Save and start server
You can select a different gamebuild from the available builds stated above, or a higher build, when FiveM announces support for it.
For higher builds, you may need to run your FiveM client in Canary, rather than release.
ENFORCING GAMEBUILD ON LINUX
On Linux, it is the exact same thing, however you need to open run.sh instead of the bat file.
txAdmin:
If you have txAdmin, you can put it in the Settings > FXServer > Additional arguments
Add the following: +set sv_enforceGameBuild XXXX - Enter the build number in place of the X’s
