Heavy Duty Viscous Center LSD 5MT purge control Failure can result in severeINCREASED 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
