ATS mods (American Truck Simulator)

Here are 229 mods for American Truck Simulator, hand-picked: trucks, maps, traffic, trailers, graphics and sound. Each mod page explains whether it's free, what the mod adds, which DLC or resources it needs and which version it supports according to its author, and links only to the author's official download: Steam Workshop, TruckyMods or the project's website. These ATS mods are reviewed with version 1.61 in mind, the current one since September 2026.

Types of American Truck Simulator mods

• Maps: expansions into Canada, improved states like Arizona, the Reforma team's maps and even Colombia.
• Trucks: Peterbilt, Kenworth, International and Mack trucks that the game doesn't include or that come heavily improved.
• Traffic: higher density and more buses in AI traffic.
• Physics: suspension, transmissions, differentials and more realistic truck and cargo behavior.
• Skins: trucking company paint jobs and liveries for trucks and trailers.
• Interiors: screens, dashboards, GPS units and cab accessories.
• Gameplay: more realistic economy, fines, weigh stations, delivery times and rest.
• Cars: mods for the cars from Road Trip: Ford, and police cruisers.

Featured ATS mods: where to start

• Project 3XX: a '90s Peterbilt with six different hoods in a single truck, from the 330 to the 379. Its author marks it as compatible with 1.61.
• Peterbilt 389 Rework: overhauls the stock 389 with 389X parts, grilles, bumpers and eight interiors. Free on Steam Workshop.
• Kenworth T660: the T600's successor, a common sight in Mexico, with a factory cab and accessories, updated for 1.61.
• Real Traffic Density: denser, more believable traffic, with rush hours, quiet nights and density based on road type.
• Traffic Trailer Mega Pack: about 500 trailers from real companies that also show up as cargo on the freight market.
• Western Canada Expansion: takes the map into British Columbia, Alberta, Yukon and other western provinces; requires all map DLC.
• Reforma Sierra Nevada: rebuilds Lake Tahoe, Yosemite, Reno and California's mountain passes.
• Realistic Rain: sharper raindrops, wheel spray and dynamic thunder; it also works in Convoy.

American Truck Simulator mods for Mexico and Latin America

If you want to drive through Mexico, the community's go-to map is Reforma. In our American Truck Simulator Mexico guide we cover which DLC it needs, the load order and how it runs on 1.61. To round it out, there's Project Better Arizona - Reforma Connection, which links Reforma with Project Better Arizona, and Reforma Esterlon, a fictional country with Mexican-American style signage. Further south, Mapkalo swaps the United States for the roads of Colombia.

ATS mods by game version

Every major American Truck Simulator update changes files that mods modify, and a mod that worked fine on 1.58 can break on 1.61. If the author has marked which versions it supports and yours isn't listed, the game won't let you activate it until it's updated. That's why every mod page shows the tested version:

• ATS 1.61 mods (current version)
• ATS 1.60 mods
• ATS 1.59 mods
• ATS 1.58 mods
• ATS 1.57 mods
• ATS 1.56 mods

How to install mods in American Truck Simulator

1. From Steam Workshop: pick your profile, open the Mod Manager and click the Steam Workshop button. When you subscribe, Steam downloads the mod and keeps it updated.
2. Manually: copy the .scs or .zip file you download from the author into DocumentsAmerican Truck Simulatormod. If the folder doesn't exist, create it with that exact name, "mod".
3. Activate it: double-click the mod in the Mod Manager and confirm the changes. Activation is per profile.
4. Set the order: the game loads active mods from bottom to top, so the one highest on the list wins if two change the same thing. With maps like Reforma, follow the order its team specifies.

If something breaks after an update, the guide to installing mods in ATS explains how to track down the culprit mod.

Can you use mods in multiplayer or on console?

In Convoy, the official multiplayer, yes: every player needs the same mods the session requires, and the ones on Steam Workshop can be downloaded without leaving the game. Sound mods are only heard by you. All the mods in this catalog are for the PC version; if you're waiting for the console version, check out what we know about ATS on Xbox and PS5.

How we choose mods

We only add mods with an identified author and an official download, and on each mod page we note the compatible version stated by its author and the DLC or resources it needs. When an ATS update comes out, we check which mods still work and update the mod page accordingly.
