The GWC Squarebody Pack for SnowRunner is a meticulously crafted mod that offers players a variety of customization options for their vehicles. This pack features three distinct nose designs from the 1975, 1985, and 1990 models, each carefully matched with corresponding hoods and fenders. Additionally, players can choose from three body styles: long bed single cab, short bed extended cab, and a Suburban variant, resulting in a total of nine possible configurations. The mod is designed to provide an authentic experience while incorporating aftermarket possibilities for extended cab pickups that were not originally manufactured by Chevrolet.

Beyond the structural options, the mod introduces unique designations such as K10, K20, and K30, along with three trim styles named Charlotte, Savannah, and Yosemite. These choices enhance the personalization of vehicles, reflecting real-life Chevrolet options. The pack also includes vanilla style tires with custom traction values, optimized for performance while maintaining low RAM usage for console players. For those seeking even more customization, an additional Scout Tire Pack is available, offering a variety of tire and wheel options.
