The Trac-Lok limited slip differential is available as
an option on Jeep vehicles equipped with Model 20 trans-
fer case only. Trac-Lok is used in rear axles only and is
not available on vehicles equipped with Quadra-Trac.
OPERATION
In a conventional differential, torque applied to the
ring gear is transmitted to the axle shafts through the
differential gears. During normal operation, torque
transmitted to each axle shaft is equal at all times.
