SLOW-N-LOW GEARING TO GO: FRO CONTROL, CRAWLING, AND CONQUERING CLIMBS, NOTHING BEATS LOW GEARS

摘要

Back in the good old days trucks were built to work, and they came with a granny low transmission and low axle gears. Ever since then true off-roaders realized that gearing is the great equalizer. Whether running stock rubber or giant aftermarket muddies, you can increase the control and capability of your 4x4 by going to lower gearing in the transmission, transfer case, or axles. We have seen amazing things done by underpowered and overtired trucks because they have super low gearing - and the reason why is torque multiplication. Every time your engine does one complete revolution per minute (rpm) it produces a certain amount of torque, and the lower the gearing the more that torque is multiplied before being put into each single rotation of the tires.
