Add-On vs Replace Vehicles in FiveM: What's the Difference?

Every FiveM vehicle is installed one of two ways: as an add-on or as a replace. Picking the wrong one causes conflicts and lost content, so it's worth understanding before you install anything.

Replace vehicles

A replace mod overwrites an existing base game car — the new model takes over an old model's name. It's common in single-player modding, but on a server it means you permanently lose the original car and can only have one mod per slot.

Add-on vehicles

An add-on spawns under its own brand-new model name and leaves every base car intact. You can install hundreds of them without conflict. This is the standard for any modern multiplayer server.

Why servers use add-on

• No limit from base game slots — add as many as your performance allows.
• Base vehicles stay available for default jobs and scripts.
• Cleaner uninstalls — just remove the resource.

When replace still makes sense

Mostly single-player, or a deliberate choice to reskin a specific base vehicle everywhere it appears in the world (NPC traffic, for example). For a roleplay or racing server, default to add-on. If you only have a replace version of a car you love, our partner GTA5 Mods Convertor can turn it into a clean add-on.

Everything in our catalog is built as clean add-on resources — browse the full car list or grab a ready pack, and follow our install guide to drop them in. For even more add-on vehicles and resources, check our partner Five Garage.
