Zeemods Store Reference

A quick guide to the terms, labels, and product types used across the Zeemods store, so you know exactly what each pack does before you buy.

Sound & Engine Packs

These provide the engine, exhaust, intake, turbo, engine brake, and driving character of the truck.

Interior & Effects Packs

These add the truck around the engine: interior controls, cabin sound, rattles, air brakes, transmission effects, and more.

ZAF Ready

This means the pack can use extra Zeemods Audio Framework features where supported.

Quick note
Zeemods products work on their own, but are designed to work together as part of a larger soundscape. If a page recommends ZAF, an Interior & Effects Pack, or another Zeemods essentials mod, it is usually because those items unlock more of the intended experience.
G3 / G4 / G5 / G5+ Sound Design Standard

The Generation label

The generation label represents the sound design standard of each product. Over time, new recording methods, editing techniques, sound layering, and extra features have defined each Zeemods generation.

360° recording

G5 packs are built with a more complete recording approach, capturing the truck from multiple useful perspectives.

Better balance

Improved depth, volume balance, and realism across interior, exterior, exhaust, intake, and camera perspectives.

ZAF integration

Modern packs are designed to work with ZAF where extra sound logic and in-game behaviour are available.

ZAF Zeemods Audio Framework

ZAF - Zeemods Audio Framework

ZAF is a Zeemods plugin for Euro Truck Simulator 2 and American Truck Simulator. It extends what compatible Zeemods packs can do by adding extra sound logic that is not normally available through the base game audio system alone.

What ZAF can add (not limited to):

Temperature-based engine fan control
Manual engine fan override where supported
Trailer reefer start, idle, run, and stop states
Dry-glass wiper drag
Detailed gear shifter, range, and splitter sounds
Separate window up/down sounds
Ignition and electrical sequences
Additional exterior effects such as park brake, ignition, and ABS self-test sounds

What “ZAF Ready” means

The ZAF Ready label means the pack has been prepared to use ZAF-related features. The exact features available can vary depending on the truck, pack, recording set, and supported definitions.

5" / 6" / 7" / 8" Exhaust Character

Exhaust diameter options

Some Zeemods engine packs are available in different exhaust versions. These are not just cosmetic labels. Pipe diameter, mufflers, and aftertreatment systems can strongly affect the tone, pulse, bass, sharpness, and overall character of the exhaust sound.

Stock

Usually more controlled, often with mufflers or emissions equipment reducing the exhaust note.

5–6"

Sharper, and often more cutting in tone, with faster and more defined pulses.

7"

A balanced middle ground, usually giving a strong mix of clarity, body, and bass (our favourite).

8–9"

Deeper and heavier, usually with more low-frequency presence and a slower, bigger exhaust feel.

Recorded differences
Each exhaust version is based on real recordings from trucks fitted with that type of setup, so the differences are part of the recording itself rather than a EQ magic.
IE Packs Interior & Effects

Interior & Effects Packs

Interior & Effects Packs are truck-specific enhancement packs. They focus on the sounds of the cab and the truck itself, rather than the engine alone. Combined with ZAF, this pack can offer some of these effects:

Interior soundscape

Switches, buttons, and levers
Wipers, windows, ignition, and warning sounds
Cab rattles, movement, and vibration
Pedal and shifter details where supported
Cabin attenuation and interior sound behaviour

External effects

Air brake effects
Parking brake behaviour
Transmission clunks and whine
Brake squeals
Other truck-specific effect details

How the Zeemods soundscape fits together

Zeemods products are designed in layers. You can use individual packs, but the most complete experience comes from combining the right sound pack, matching interior/effects content, ZAF, and recommended supporting mods.

Layer 1
Engine sound

Sound & Engine Packs provide the main engine character.

Layer 2
Truck detail

IE Packs add the cab, controls, air systems, and truck effects.

Layer 3
Extra logic

ZAF unlocks additional behaviours and sound triggers.

Layer 4
Environment

Supporting mods fill out wind, tires, trailers, reverbs, and weather.
