All Wrangler JKs can be optioned with up to 32-inch tires (255/75R17), but to help troubled dub-lovers like our own Senior Editor Brubaker to sleep at night, 18-inch wheels are available (P255/70R18). Thanks to the 32s, running ground clearance is over 10 inches, up about 1/2 inch over the TJ. Out on the Rubicon are the Goodyear MT/Rs, replaced with smoother and quieter BFGoodrich M/Ts. All wheels have been upgraded on the JK since the bolt pattern has grown to 5-on-5.
Longer-travel coil springs can be found at each corner, and a five-link similar to the TJ is in the rear. Swaybars are available front and rear, and the Power Wagon-style electronically disconnecting swaybar that's standard on the Rubicon is optional on other models. Sahara and Rubicon models come standard with monotube shocks, while the X trim level makes do with twin-tubes.
The JK's cabin is a huge improvement in comfort and refinement. | 
With the seats folded, there is plenty of room for gear-88.3 cubic feet, to be exact. |
As with the two-door JK, the unlimited is available wih a three-piece removable hardtop. | |
Increasing the occupant comfort and convenience was a major goal for the JK program. So now, a range of upgraded audio systems, including navigation, are available, as are power windows and door locks. And yes, the doors are still removable and the windshield still folds down. Half doors will be available on the Unlimited, as well as a removable three-panel hardtop. The Sunrider soft top is standard, but for those who enjoy motoring top-down, there are drain plugs in the floor and special carpeting that won't mildew. Of course, the JK also offers gobs of interior room behind the more comfortable seats. The Unlimited has two more inches of legroom and accommodates three across, bringing the passenger count to five, whereas the two-door is strictly a four-seater. A respectable 44.6 cubic feet of cargo space (with the seats up) and an expansive 88.3 cubic feet (with the seats down) translates in to a 5-foot, 6-inch load floor.
Because of the longer wheelbase, the tow rating for the Unlimited is 3,500 pounds, 1,500 pounds higher than the two-door's. Anticipating that customers will use their hitch for a recovery point, engineers equipped the JK with a fullsize Class III hitch for shackles and other recovery gear. The Unlimited will also be available in a two-wheel-drive version.
Lastly, for those of you plotting ways to upgrade your TJ with JK bits, the only two parts that are interchangeable are the rear tailgate lock cylinder and the footman loop on the hood.
What's Hot
Everything is bigger, rugged new platform, four-doors, still a Jeep.
What's Not
Is it too long?
Our Take
XJ fans, rejoice-your Cherokee replacement has finally arrived.
The 205hp 3.8L OHV V-6 is the only engine available in the '07 Wrangler. | 
The Unlimited has an additional 2 inches of rear-seat legroom, and with its wide rear door openings has better ingress and egress than either a Cherokee XJ or Liberty. |
The '07 Wrangler Unlimited is impressive on paper and in person, but we can't wait to get our hands on one to test on the trail. | |
