Claim


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.

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.
