4 wheel drives allow the driver to traverse even the toughest of terrains. Even if your car does not come with a built in 4 wheel drive, it’s not too late, It’s all in the transmission! 2 wheel drive automatic and manual transmissions can be converted into 4 wheel drive cars for a more rugged ride no matter what your ride is. By the time they’re finished, 4 wheel drives and converted 2 wheel drive automatic and manual transmissions are almost perfectly identical in terms of housing and gear ratios. Where these two will sometimes differ is that these transmissions will sometimes differ in spline count on their output shafts.
How Do 4×4 Four Wheel Drives Operate?
4 Wheel Drive systems provide the additional traction needed for off roading and standing up to harsh conditions. 4×4 vehicles utilize what is called a drivetrain to operate. The drivetrain uses two differentials and a transfer case to supply power to all four wheels rather than just two. Four wheel drives provide an added level of versatility as opposed to most all wheel drive vehicles. With a two differential system, four wheel drive systems can often be switched on and off, so you can keep two wheel drive capabilities for easier roads to save on fuel economy.
