Two steps reduce gearbox STAGES in gear box basically means increasing the gear ratios at one level so that the vehicle gets variant torques specifically to negotiate a particular terrain. In most cases these ratios are tuned by taking account of various factors like net weight , number of cylinders and the terrain in which the vehicle is choosed.The need or the concern for a 2nd stage in a gear box comes whenever torque reduction or multiplication is needed for efficient traversal in varying landscapes.
