the lighter oil in the rear helps keep the rear end planted and push the truck through the turn were as heavier oil in the front diff helps pull the truck through. The front end will remain planted in the turns no matter what so thicker oil will benefit there but with the lighter oil in the rear when a tire does come off the ground more power is given to the wheel off the ground and that puts it back on the ground and there for pushes your truck through the turn.
