* Improved Acceleration: It limits wheelspin. When one rear wheel starts to lose traction (spinning), a positive traction system like a limited-slip differential (LSD) or electronic locking differential redirects power to the wheel with more grip. This allows for better acceleration and prevents getting stuck.
* Enhanced Handling: Better traction improves handling, particularly when cornering on loose surfaces. The system helps maintain control and prevents the rear end from sliding out.
* Increased Stability: By distributing power more effectively, it leads to more stable handling, particularly during acceleration or when encountering uneven terrain. This is important for maintaining control and preventing loss of traction.
Different types of positive traction systems work in slightly different ways:
* Limited-slip differential (LSD): This mechanically limits the difference in speed between the two rear wheels. If one wheel spins, the LSD sends more power to the wheel with traction. There are several types of LSDs with varying levels of engagement.
* Electronic locking differential (ELD): This uses electronic sensors and actuators to lock the two rear axles together, forcing them to rotate at the same speed. This provides maximum traction in extreme conditions but can be less ideal for on-road driving.
In short, a positive traction rear end makes a 4x4 F-150 significantly more capable off-road and in slippery conditions by maximizing traction and improving handling. It's a key feature for anyone who frequently drives in challenging environments.
