How to Increase Your Vehicle's Gross Vehicle Mass

The gross vehicle mass, or GVM, is the weight and mass a vehicle can manage on its own wheels and with standard, factory-installed parts. Hauling more weight than the GVM puts undue strain on the engine, transmission and axle, and overheats a vehicle very easily. You also might not be able to brake safely and bring your vehicle to a stop quickly enough when you exceed its GVM. If you must haul loads heavier than the recommended GVM for your car or truck, discuss your needs with a mechanic or other professional.
