Which is faster, a 4.33 ratio or a 4.875 ratio?

[BethanyAnn]

4.33 ratio provides higher speed, while the 4.875 ratio offers better power. The 4.875 ratio is more suitable for heavy loads. The vehicle's transmission serves to change speed and torque, and the differential contains a main reduction gear to further reduce speed and increase torque. When the engine operates, it runs at high RPM, requiring the transmission to reduce RPM and increase torque for normal vehicle operation. Below is relevant information about gear ratios: 1. Different gears in the transmission have different ratios, and different vehicles have different main reduction gear ratios in their differentials. 2. A larger ratio results in slower speed but greater torque, while a smaller ratio leads to higher speed but less torque. Typically, torque refers to the output torque at the engine crankshaft, which is the moment that causes an object to rotate. The engine's output torque is amplified by the transmission and main reduction gear, converting it into wheel torque. 3. The main reduction gear ratio in a vehicle's differential is fixed, and different vehicles have different main reduction gear ratios in their differentials.
