Gearless Centre Differential

Our premium product is the GEARLESS CENTRE DIFFERENTIAL transfer case conversion for the Toyota Landcruiser HZJ 75/ 78/ 79 & VDJ70.

This converts the standard part-time transfer case into a full-time four wheel drive, making it the perfect 4WD differential. It functions as an automatic lock-unlock driveline torque balancer to prevent destructive axle wind-up when operating in 4WD continuously on hard surfaces.

These forces are caused as the front outside and rear inside wheels travel different distances especially during tight cornering.

By automatically indexing during cornering, to neutralise windup, the GEARLESS CENTRE DIFFERENTIAL always acts with a full differential action through the transfer case between the front and the rear prop shafts.
