* Acceleration on loose surfaces: With an open differential (the standard setup in most vehicles), power goes to the wheel with the least traction. This means if one rear wheel is on ice or loose gravel, it can spin freely, leaving you stuck. A positive traction rear end sends power to *both* wheels, even if one has reduced grip. This allows for better acceleration and launch.
* Cornering on loose surfaces: Similar to acceleration, when cornering on loose surfaces, an open differential can cause the inside wheel to spin, leading to loss of control. A positive traction rear end helps maintain traction and control during turns.
* Towing and hauling: When towing or hauling heavy loads, a positive traction rear end provides improved stability and prevents wheelspin, leading to safer and more controlled driving.
In short, for a V6-powered 2WD GMC 1500, a positive traction rear end makes a substantial difference in its ability to get moving and stay moving in challenging conditions. The V6, being less powerful than a V8, will benefit even more from the improved traction as it has less torque to overcome wheelspin.
