Advice to GVJ DiffsIs not an Open Differential, nor a Limited slip Differential, nor anActive Differential or any other of the contemporary differentials.GVJ Differential is a patented, new, intelligent mechanicaldifferential system, totally advantageous to all the differentials

currently known, free of biasing and itsusual drawbacks.It allows precise differentiation, avoids wheel slip, and assures apermanent traction.

Mechanical and safety advantages:

Allows the right differentiation.Avoids wheel slip.Avoids the halt of one wheel if the other rotates.With a wheel missing ground, the other gets full torque.Unnecessary Torque Control Systems.Compatible with ABS, ESC, and other safety systems.Light and robust.
