Larger tires on lifted truck suffer from loss of power, changing the ring gear and pinion to a lower ratio is the answer. Changing rear end ratio can improve fuel mileage, reduce and extend engine life, and/or add additional power for your towing requirements.
Why you need a positraction?
Without positraction only one rear wheel receives the power. In bad road conditions say, mud, ice or snow traction to one wheel is bound to get you stuck. Installing a positraction provide power to both wheels at the same time, a significant improvement in traction. For positraction replacements and parts see the following link. Positraction units are available for many General Motor FWD Front Wheel Drive models.
