FRONT SWAY BAR DISCONNECT SYSTEM
With the flip of a switch, the sway bar
automatically disengages when driving
under 18 mph in 4WD-low (4LO) mode.
This allows the front wheels to drop
and compress up to 22 percent further
on Wrangler or 25 percent further on
Wrangler Unlimited (standard on
Rubicon, available on Unlimited X).
RUN SMOOTHLY ON THE EVEN ROAD Low
spring rates help provide awesome
articulation and a quality on- and
off-road ride.
TRU-LOK ® LOCKING DIFFERENTIALS Front
and rear electronic-locking differentials
balance speed between left and right
wheels, maintaining forward momentum
for the ultimate in Wrangler traction. The
instrument panel-mounted rocker switch
can lock either the rear or both axles
(standard on Rubicon, rear locking
differential only available on Unlimited X).
DRIVESHAFTS Shafts are harmonically
quiet thanks to bending stiffness and
precise balancing.
COMMAND-TRAC ® TRANSFER CASE
A NV241 G11 transfer case is smooth,
quiet, and tough. Ribs and a stiff outer
case also reduce the potential for
leakage (standard on Sahara and X
4WD models).
ROCK-TRAC ® TRANSFER CASE A 4:1
low-gear ratio allows Wrangler Rubicon
to crawl at a low speed for greater
control and increases the amount of
torque available at the wheels (standard
on Rubicon).
TWO-PIECE STRUCTURAL OIL PAN
A two-piece oil pan provides a steel
lower portion for impact resistance with
an upper aluminum section for improved
noise reduction and weight savings.
BEST-IN-CLASS GROUND CLEARANCE (1)
Rubicon’s standard 32-inch BF
Goodrich
® off-road tires have
a custom tread pattern that is
exclusive to the Jeep
®
brand.
NEXT GENERATION DANA 44 HEAVY-DUTY
SOLID AXLES
Durability and articulation
come from heavy shafts, stiff housings,
large pinion bearings, and above-center
pinion mountings. The above-center
mounting helps reduce driveshaft joint
angles for smoother, quieter operation,
and also adds ground clearance (Rear
Dana 44 standard on all. Front Dana 44
standard on Rubicon).
BODY-ON-FRAME DESIGN Fully boxed for
strength, stiffness, and durability.
TORQUE TO TOW Unlimited can
confidently tow up to 3,500 lb when
properly equipped with the factory-
installed Trailer Tow Package.
TUNABLE MONOTUBE SHOCK ABSORBERS
A proprietary Low-Speed Tunable (LST)
valve technology is firm at low speeds
for improved feel on rocks and offers a
more relaxed feel at higher speeds for
optimum highway driving (standard on
Sahara and Rubicon).
OFF- AND ON-ROAD BRAKE SYSTEMS
A four-wheel disc antilock brake
system (ABS) with a Jeep 4WD
off-road calibration system provides
more sustained wheel lockup on
plowable surfaces — like mud, sand,
and gravel — than normal ABS for
improved stopping performance
(standard on all Wrangler 4WD models).
ROCK RAILS Extra-tough body-mounted
rails provide additional protection
(standard on Rubicon).
DRIVE BY WIRE The Electronic Throttle
Control (ETC) system helps prevent
the “pedal bobble” that often occurs
when in 4WD-low (4LO) mode (when
equipped). ETC’s special off-road
calibrations help the driver to “feather
in” the throttle over uneven terrain,
logs, and rocks. The difference is night
and day and is akin to walking versus
bouncing along tough off-road events.
SKID PLATES Stamped steel skid plates
for fuel tank, transfer case, and
automatic transmission oil pan help
protect Wrangler’s guts when battling
boulders and jagged rocks (standard
on 4WD models).
KEEP STEERING ON COURSE Wrangler
features a steering linkage and a
recirculating-ball steering gear. Its
robust, cross-link geometry offers the
stiffest possible linkage system in a
solid-axle platform for steering
precision and BEST-IN-CLASS
turning diameter.

HEAVY-DUTY SUSPENSION Solid axles
with locating arms, coil springs,
track/stabilizer bars, front steering
damper, and high-pressure gas-
charged monotube shock absorbers
are comfortably capable (standard
on Sahara).
