Upgrade your American Truck Simulator experience with the Ultimate Pack — the most advanced version of Realistic Truck Physics for ATS.

Compatible with all default ATS trucks, plus dedicated support for a growing range of popular truck mods.

The Ultimate Pack includes three carefully tuned presets. Think of them as three different physics mods in one package — simply choose the driving experience you prefer:

Flexible – Increased suspension travel and dynamic cabin movement
Realistic – Balanced setup based on real-world truck behavior
Stable – More controlled and predictable handling

You can switch between presets at any time through the in-game Mod Manager.

Recommended Gameplay Settings

These settings were used during the development and testing of this physics mod. The behavior shown in previews and described on the mod page is based on this configuration.

The required settings directly affect the game's physics calculations. Changing them will not break the mod, but the truck and trailer will behave differently than intended, and the driving experience may no longer match what is advertised.

The optional settings do not affect the physics preset itself. They are simply my recommended gameplay preferences and can be adjusted freely without changing the mod's physics behavior.

Required

Truck stability: 100%
Cabin Suspension Stiffness: 100%
Suspension Stiffness: 100%
Trailer stability: 100%

Optional

Driveshaft Torque: 100%
Braking Intensity: 100%
Uneven Surface Simulation: 100%
