Pretty nifty, right?
Understanding The Dana 20 Overdrive Mechanism
The Dana 20 transfer case, produced by Dana Corporation, has been found in a variety of classic four-wheel drive vehicles for decades. From the 1960s to the late 1970s, it was an integral part of popular vehicles like the Ford Bronco, Jeep CJ, and International Scout. What makes this model stand out is notably its durability and dependability.
The Dana 20 overdrive can effortlessly kick into a higher gear due to a bi-directional overdrive unit. It involves a planetary gear system — this means the gears revolve around a central, or ‘sun’ gear, like planets orbiting in a solar system. Thus, the overdrive unit adjusts the speed and torque delivered to the wheels, resulting in less strain on your car’s engine while maintaining optimal speed.
