AUTO TORQUE FRONT DIFF CENTRE

Our ATB diff lock is fully automatic and progressive in operation. Unlike conventional diff locks and LSD’s , ATW’s will never lock but will seamlessly and progressively transfer power and torque away from a spinning wheel to the one with the most traction. This is the opposite action of an OEM ‘open’ diff which in soft or loose conditions will promote wheel spin and loss of drive. In off road situations, the ATB diff significantly reduces torque steer, under steer and steering ‘snatch’ associated with common clutched type LSD’s and air or electric diff locks. 

When off-road, this translates into reduced wheel spin (improved tyre life), virtually no torque steer and less under steer during cornering (improved safety and control)…..most importantly, it will greatly enhance performance and drive in soft mud and sand, therefore reducing the chance of getting stuck and the need for recovery. If one wheel is lifted from the ground so that there is no torque bias, the diff will revert to the same operation as an open diff, however simply tapping the brakes will be enough to regain maximum torque to the opposite wheel still in contact with the ground. 

The ATW Auto Torque Biasing (ATB) Helical Gear Limited Slip Differential (LSD) is a direct replacement for the front axle OEM factory ‘open’ differential centres on all Fuso FG Canters and Isuzu NPS.
