What this mod does

Diamante Negro LT is the free version of the customized International LT by the RBL MEXA RTM and El Rojo Truckers México team: an all-black highway truck in the style of Mexican fleets, made to stand out in convoys and on long hauls.

What it includes

  • Custom body with 3 new bumpers and 3 new grilles, extra lights and exclusive accessories.
  • Several visual configurations to mix parts as you like.
  • Interior with its own details, a refined dashboard and better lighting.
  • High-quality textures, optimized materials, reflections and lighting effects.

Install and purchase

Enable it in the Mod Manager, load your profile and buy it at the mod dealer (“Modified Brands” section). It weighs about 2 GB. It was released on June 5, 2026 and last updated on August 28, 2026 (“optional conversion”); earlier updates fixed bugs, repaired the grille and added 6 new parts.

Keep in mind

The authors ask you not to combine it with other International LT mods or modifications of that truck: unsupported accessories can cause missing parts, odd textures or crashes. They say it is compatible with recent ATS versions but give no specific version number.
