What this mod does
Additional Parts for 9900i is a parts pack by guidot, the author of Project 3XX, for SCS’s official International 9900i. It adds options to make your 9900i stand out without switching trucks or replacing the original model.
Included parts
- Stripped Guides and a Flare bumper with guides.
- Paintable filters and guides-only filters.
- Paintable tanks.
- Short exhaust stacks (Short Stacks).
- Thicc Stacks, chunky exhausts contributed by UROGaming Specialty.
Requirements
You need the International 9900i DLC, since the parts fit on that truck. The page doesn’t require any other mods.
Version and compatibility
The latest version is 1.03a. In it, the author removed the lowered chassis the pack used to include, because SCS added the option to raise and lower the suspension to the game. On TruckyMods he marks it as compatible from 1.44 to 1.61, and the page was last updated on September 20, 2026.
From the same author
guidot also publishes Project 3XX, with ’90s Peterbilts, and Project 389, a parts pack for SCS’s 389.
License
It’s released under the MIT license, although the page asks you to get the author’s permission before reuploading or modifying it. Always download it from its own page.
