Axle gearing plays a critical role in vehicle performance. It determines how efficiently engine power is delivered to the wheels, which directly impacts fuel efficiency, torque, acceleration, and the ...

Optional axle ratios can tailor pickup truck power and efficiency to suit your needs as long as the gearing keeps the engine in its torque sweet spot. Often overlooked, optional gear ratios play a key ...

If you’re new to four-wheeling then you’ve probably heard about changing gears and adding lockers. If you pictured shifting your transmission with locking boxes in the bed, that is not what we are ...

Put simply, gearing makes things turn faster or slower, or trades speed for torque. With it we can make our vehicles fly across terrain at crazy fast speeds or crawl super slow over boulders. Big ...

Vehicle speed (mph), engine speed (rpm), tire diameter (inches), trans gear ratio, and rear axle gear ratio are all interrelated. If you know four out of five of these values, you can determine what ...

Engineering legend has it that Atlas, doomed to perpetually bear the weight of the world on his shoulders, lamented, "Give me a lever long enough, and I can move the world." Atlas realized that levers ...
