One thing to take into account is how some differentials make the clicking noise. To some it may be music to their ears but for me Quiafe makes a lsd that uses gears and not clutches. Another difference is that Quiafe transfers more power to the tire with more traction as opposed to other LSD's that transfer power to both wheels evenly regardless. Man, i feel like a Quiafe sales representative.
P.S. Correct me if i'm wrong.
