Jeep
Wrangler JT Concept
PRESS
RELEASE: Chrysler teamed up with the guys at
Skunkwerks to build the long waited for Jeep truck.
Based on the JK Wrangler Unlimited the truck
features all that is found in an unlimited along
with a 5 foot bed. Skunkwerks equipped the
Jeep with a 3" lift, 35" BF Goodrich Mud-Terrain
tires, and a Ramsey winch.
According to Mark Allen, Jeep senior manager of the
Product Design office, the JT was created from a
chopped-up, two-door hardtop JK model with the
addition of the steel bulkhead to divide the
passenger compartment from the cargo area (from a
Dakota pickup box). The JT is fitted with a
five-foot truck bed cargo box measuring 47 inches
wide by 61 inches long and sports a side opening
tailgate as well as a removable top. The JT's pickup
cab compartment retains the factory JK sport bar and
the chassis uses the coil spring rear suspension of
the civilian model JK (the military J8 has uses a
Dana 60 and leaf spring suspension).
The JT truck
prototype used the following:
- Stock 3.8L V-6
- Four-speed
automatic transmission
- NV2414:1 Rock-Trac
transfer case
- Front and rear
Dana Model 44 axles with Tru-Lok electronic
lockers
- BFGoodrich
35x12.50R-17 Mud Terrain T/A tires mounted on
Custom 17x8-inch steel wheels from Stockton
Wheel (the JT was lifted to accommodate 35-inch
MT tires)
- American
Expedition Vehicles new Heat Reduction hood
- Ramsey 9500 UT
winch
- American
Expedition Vehicles JK front winch mount
- Mopar rear
bumper
- Paint color
called Hearing Aid Beige (...yes that's right?)
- Aftermarket Hood
- Some in-cab
components are from
AEV (American
Expedition Vehicles)

Motor Trend gave the Jeep a once over and
provided some images along with the Chrysler
marketing photos. Some of the images
feature the JT tackling the trails of Moab.

Our opinion
Jeep should
build this, period. A small truck capable of carrying
light loads and getting in and out of the trail confidently
is a niche that stretches back to the days of the Commanche
pickup. Built on the reliable Wrangler platform and
sharing lots of parts is a plus for the aftermarket.
One request to Jeep...no swinging rear gate...a true truck
has a drop down tailgate.
