The Squarebody Maxx Addon Pack is a versatile mod for SnowRunner, designed to enhance the customization options for Squarebody trucks. This free addon pack includes a variety of custom parts that are compatible with several truck models, such as the Classic Crew, Shorty Squarebody, and Squarebody Dually. The pack focuses on providing players with interchangeable parts, allowing for a tailored experience while maintaining the integrity of the original truck designs. With options like multiple bumpers, bed racks, and different bed styles, users can create unique setups for their vehicles.

The addon pack is a separate download, aimed at optimizing performance by reducing RAM and file size. This decision caters to players who prefer using a basic truck for campaign scouting without unnecessary clutter. The included customization parts are designed to be easily integrated into the game, with automatic availability in the garage for compatible trucks. Additionally, there is a PC-exclusive emblems pack that further enhances the aesthetic appeal of the Squarebody models.
