The GMC Sierra Phantom is a full custom take on GMC's full-size pickup: a blacked-out, slammed dually built to be a show truck rather than a work truck. It comes to GTA V Enhanced as a standalone add-on — original model by Heat, with custom work by DimoSerb — so it drops into your garage without overwriting any stock car.

The screenshots make the theme clear. It sits low over wide chrome dually wheels, wears a widebody stance with the red GMC grille badge and a 6.2L V8 fender emblem, and glows: signature illuminated spiked wheels that change colour with the rim, plus underglow in the night shots. The custom extras are the fun part — a matte black tonneau cover, a gloss black tonneau cover, a front off-road light bar, roof bullet lights and an exhaust that exits through the bonnet — all toggleable from a trainer. It is a proper street-show dually.

Installation follows the usual 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 the custom engine sound by Streiter_V12 and one with the stock GTA engine audio, for players whose games already carry other sound add-ons that would conflict with it.

Original model by Heat; custom engine sound by Streiter_V12; custom work by DimoSerb. 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 truck with a trainer using the name 21sierra.

Frequently asked questions

How do I spawn the GMC Sierra Phantom?

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

What are the custom extras?

The truck ships with signature illuminated wheels that change colour with the rim, a matte and a gloss black tonneau cover, a front off-road light bar, roof bullet lights and an exhaust routed through the bonnet, all toggled from a trainer.

The engine makes no sound — what happened?

Other engine sound add-ons can conflict with the custom audio by Streiter_V12; 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.
