Heavy Duty Viscous Center LSD TY75 6MT (Cable Shift)

INCREASED TORQUE TRANSFER

Uprated center viscous diffs are engineered to provide either a 20kgf-m/100rpm or 12kgf-m/100rpm torque transfer rate compared the 4kgf-m/100rpm factory specification. LSD response and durability is increased while traction on loose surfaces is significantly improved. However, tight cornering understeer on pavement can be a problem when the transfer rate is very high. For this reason it is suggested that a 20kgf viscous only be used primarily for gravel and loose surfaces while the 12kgf unit can be used with much less adverse effect on pavement and is more suitable for street and track use.

The purpose of a differential is to allow independent rotation of wheels across the axle (front, rear, or center in an AWD application).  This is necessary due to the variation in rotational speed while cornering due to the different arc radii that each wheel travels.  A viscous LSD is speed sensing meaning that the LSD reacts to a speed differential between the two axles.  A viscous silicone fluid acts to transfer torque between opposing splined plates allowing torque to be transferred to the wheels with greater traction.
