Gear Ratio

GEAR RATIO

This is a numerical ratio of a series of gears in relation to each other, based on the number of turns of the input shaft, compared to turns of the output shaft. Gear ratios are determined by the number of teeth on each gear (and therefore the size of each gear). Ground Clearance

GROUND CLEARANCE

Ground clearance is the measurement from the lowest-hanging point under a vehicle (usually a differential, part of the suspension or the exhaust system) towards the ground. A high ground clearance allows a vehicle to drive more easily off-road or through heavy snow without damaging the underbody.
