because Kaiser allows the wheels to rotate at different speeds and delivers torque based on each tires individual RPM.Cool but why Kaiser vs ARB?
Lets say you are fully locked and taking a left hand turn. So the rear left wheel travels the shortest distance, then the left front tire, right rear tire and finally the right front tire
ARB, all 4 tires are linked and trying to turn at the same speed causing drive line binding and if you are on pavement, tires chirping and hard steering as the truck wants to only go straight.
Kaiser, all 4 tires rotate at different speeds and the torque supplied is proportional to each tire's RPM
