Master the Terms of Vehicle Axle Gear Ratios! Unleash your vehicle's full potential by mastering the essentials of axle gear ratios. This knowledge isn't just technical jargon; it's your key to optimizing performance and efficiency on any terrain. Whether you're climbing steep hills or towing heavy loads, understanding gear ratios will empower you to make informed decisions that enhance your vehicle's capability and longevity. Dive into the mechanics of axle gear ratios and take control of your driving experience with confidence. The axle ratio is sometimes called the gear ratio. Also, lower axle ratios are referred to as tall gears, and higher ones as short gears. Put simply, trucks with tall gears make fewer engine revolutions per a given speed or wheel spin. Hence they achieve higher fuel economy but have less power or torque. Conversely, trucks with short gears make more engine revolutions per a given speed or wheel spin, providing more power or torque but lowering fuel economy.
