What this mod does

Realistic Truck Physics Mod by Frkn64 is the most popular physics mod for American Truck Simulator: it has over 420,000 subscribers on Steam Workshop. The author has been updating it since 2016 and tweaks the suspension, transmission response and camera movement.

What it changes

  • Better-balanced chassis suspension.
  • Cab movement that responds to the road and the truck’s weight.
  • Trailer physics that react to the terrain and the load.
  • Smoother interior camera.
  • Driveshaft torque simulation.

Game settings

The author asks you to set truck and trailer stability, suspension stiffness and cab stiffness to 100%. Driveshaft torque, braking intensity and uneven road simulation at 100% are optional but recommended. In the comments, the author mentions braking at 50%.

Version and compatibility

Version 9.2 adds 1.61 compatibility and a small physics improvement; the author lists 1.61.x and 1.60.x. The author says it works with all current ATS trucks and optionally supports Convoy. Separately, the author sells an Ultimate Pack with presets and support for modded trucks.
