Engine upgrades
Engine upgrades determine a truck’s power; the guide suggests using item descriptions and the vehicle’s Power-To-Weight rating to compare options.
Understand this choiceSnowRunner is a vehicle simulation in which players drive across rough terrain to complete objectives. The supplied guide describes vehicle performance choices including engines, gearboxes, suspension, tires, and differential lock, alongside utility options such as winches, spare wheels, snorkels, and frame add-ons. It gives concrete effects and constraints: raised suspension may help in deep water but can make a vehicle easier to roll, while spare wheels add weight. The records below explain these named choices and the distinctions the guide makes between them. The source passages do not provide a complete catalog, exact costs, or vehicle-by-vehicle compatibility, and do not establish availability across PC editions or DLC.

Understand this choiceGearboxes determine which drive settings are available; the guide gives Freeway as an example for a truck mainly used on asphalt roads.
Understand this choiceRaised suspension may help when trucks take engine damage over large bumps and may help prevent engine failure in deep water, with a rollover tradeoff.
Understand this choiceTires are grouped by use and receive Wheel Performance ratings; the guide names All-Terrain and Off-Road as options to consider when starting out.
Understand this choiceDifferential lock locks the rear tires into one constant motion; the guide describes it as situational but often essential for getting out of difficult situations.
Understand this choiceA winch can attach a rope to structures, trees, or vehicles to pull out, prevent rolls, or retrieve drowned vehicles; Scout options differ in strength and availability.
Understand this choiceAn onboard spare wheel may help after a tire is lost on a long trip, but the guide says it adds weight to the vehicle.
Understand this choiceA snorkel protects the engine from water damage; the guide gives swampy bodies of water in Taymyr as an example context.
Understand this choiceFrame add-ons provide repair-item storage and extra fuel options for scouts, and beds or machines that attach to larger trucks.
Understand this choiceHigh and Low Saddle options are described as free; a required trailer may call for one type, and saddle height cannot be changed outside the garage.
Understand this choiceA source-bounded reference to vehicle performance upgrades and utility choices described for SnowRunner. It covers stated functions and restrictions, not exact costs, complete compatibility, or comparative effectiveness beyond the supplied descriptions.
