Quadra-Drive II System – If
Equipped
The optional Quadra-Drive II System features
two torque transfer couplings. The couplings
include an Electronic Limited-Slip Differential
(ELSD) rear axle and the Quadra-Trac II trans-
fer case. The optional ELSD axle is fully auto-
matic and requires no driver input to operate.
Under normal driving conditions, the unit func-
tions as a standard axle, balancing torque
evenly between left and right wheels. With a
traction difference between left and right
wheels, the coupling will sense a speed differ-
ence. As one wheel begins to spin faster than
the other, torque will automatically transfer from
the wheel that has less traction, to the wheel
that has traction. While the transfer case and
axle coupling differ in design, their operation is
similar. Follow the Quadra-Trac II transfer case
shifting information, preceding this section, for
shifting this system.
