What is a posi rear end?

A posi rear end, short for positive traction rear end, refers to a type of differential that distributes power evenly to both drive wheels of a vehicle, offering better traction and improved handling. This type of rear end is commonly found in high-performance vehicles, sports cars, and trucks, as it helps maximize power transfer to the wheels, especially during acceleration.

Posi rear ends use a mechanism that prevents one wheel from spinning faster than the other, which is especially useful in situations where one wheel may lose traction, such as when driving on slippery or uneven surfaces. This helps improve overall stability and control of the vehicle.

Posi rear ends are also commonly referred to as limited-slip differentials, as they provide some level of resistance to wheel slippage, preventing one wheel from effectively going into a spin. This makes them ideal for performance driving, off-road use, and towing applications.

Overall, a posi rear end can greatly enhance the driving experience by improving traction, handling, and performance, making it a popular choice for enthusiasts and automotive enthusiasts.
