Can someone explain to me in laimens (spl) terms the difference between the two. Pro's and cons of the two. Both are stock gears. Also why were talking about gears. If a whole differentail were to be submerged in water for a long period of time (days). How would it effect the insides and what would have to be done to assure it is fixed. Thanks. Reason being, I just got a rear end from a flood vehicle that has 3.55 gears. Thanks for the help.
