The GMC Sierra is one of America's default full-size pickups, and this widebody build gives it a lower, meaner stance without turning it into a cartoon. This add-on by Heat brings the 2021 Sierra to GTA V Enhanced as a standalone vehicle with its own dlcpack, so it never overwrites any stock truck in your game.

The model keeps all the details that read as a GMC on screen: the red GMC lettering in the C-shaped grille, the SIERRA badge across the tailgate, the 5.3L V8 fender emblem and the 4x4 decal on the bed side. On top of that stock look it wears a widebody kit with flared rear fenders, a front splitter, chrome tow mirrors, roof marker lights and a set of black alloy wheels. The interior is fully modelled: sit inside and you get the GMC multifunction steering wheel, a working digital instrument cluster and a central infotainment screen with its own menu layout, as shown in the first-person screenshot. Open the bonnet and the engine bay is there too.

Installation is the standard add-on route: drop the folder into dlcpacks (mods or onigiri), register dlcpacks:/21sierra/ in dlclist.xml and spawn it with a trainer under the name 21sierra. The original release ships two downloads: one with a custom engine sound and one with the stock GTA engine audio, for players whose games already run other sound add-ons that conflict with it.

Original mod by Heat. Converted for GTA V Enhanced by DimoSerb. Hosted on GTA6 Cartel with the author's permission, with the original Nexus release linked as the source.

Requirements

  • GTA V Enhanced (PC)
  • OpenIV (mods folder) or onigiri
  • A trainer to spawn the vehicle (e.g. Menyoo)

How to install

  1. 1Copy the contents of the folder to \mods\update\x64\dlcpacks (or to onigiri\dlcpacks).
  2. 2With OpenIV, go to update.rpf\common\data and open dlclist.xml (with onigiri: open onigiri\common\data\dlclist.xml in Notepad).
  3. 3Add the line <Item>dlcpacks:/21sierra/</Item> and save.
  4. 4Spawn the vehicle with a trainer using the name 21sierra.

Frequently asked questions

How do I spawn the GMC Sierra WideBody?

Install the add-on, register dlcpacks:/21sierra/ in dlclist.xml and use a trainer with the spawn name 21sierra.

Is this a replace or an add-on?

It is a standalone add-on with its own dlcpack, so it does not overwrite any stock GMC or truck. Note it uses the dlcpack folder name 21sierra, so if you also run the GMC Sierra AT4 conversion you would need to rename one folder.

The engine makes no sound — what happened?

Other engine sound add-ons can conflict with the custom audio; the issue is known since the Legacy version. The original release includes a second download with stock GTA engine sounds — use that one if you are affected.

Does it work on GTA V Legacy?

No. This conversion targets GTA V Enhanced and its dlcpacks structure.
