Get up to speed on regearing your vehicle.
Your vehicle's axle gearing is determined by the amount of teeth on the ring and pinion gears, which in turn dictates how many times your driveshaft needs to rotate the wheels once. So if you're a serious off road driver you may want to look at regearing to maximise your drive experience.
When why should you regear your vehicle?
If you do plenty of motorway driving on small to medium tyres, you may want to consider regearing to a "taller" set of gears in order to boost your maximum speed and fuel efficiency. Conversely if you mainly off road or have larger tyres fitted, you may want to regear to shorter gears.
