American Expedition Vehicles (AEV) to offer limited number of 2010 J8's

The J8 is one of the toughest vehicles in the world and, until now, it was only sold to foreign militaries and governments. A very limited number of 2010 J8's will be made available to enthusiasts in the United States exclusively from American Expedition Vehicles (AEV) as the AEV J8 MILSPEC.

Walled Lake, MI (PRWEB) April 9, 2009 -- "Hardcore off-road enthusiasts have been asking for a vehicle like this for years, no frills and setup for a choice of diesel or V8 power and built with extra heavy-duty components," said Dave Harriton, CEO of American Expedition Vehicles. "It's certainly not for everyone, but that's all part of the appeal. Being able to offer even limited quantities to the American public is really a dream come true for AEV. First, it's a perfect match with our niche manufacturing and distribution channels, and second, the J8 is a unique part of history that we're proud to be part of."

The AEV J8 MILSPEC will be sold as a component rolling chassis. The vehicle is meant for off-road use, and as typical for component vehicles the engine and transmission will be installed by the buyer or at the buyer's direction by an independent contractor. Although AEV does not provide the powertrain, there are a number of independent AEV dealers that can supply and install either a 2.8-liter diesel engine or a 5.7-liter V-8 HEMI® engine and transmission package.

The J8 MILSPEC will be assembled in Detroit by AEV. The complete rolling chassis will be delivered painted, upholstered, fully instrumented and will include ABS brakes, heavy duty suspension and axles, exhaust, wheels and tires.

Designed for military use, the J8 was designed to pass one of the world's toughest durability cycles, which is three times more severe than what civilian applications must endure. The axles are both beefed up to a heavy duty Dana 44 front and a Dana 60 rear axle equipped with Dodge Ram brakes. The frame is built for severe use and the rear suspension uses leaf springs to facilitate more than a 2,500 lb. payload capacity and a 3,500 lb. tow rating. The J8 MILSPEC will accept two powertrain options, either a VM 2.8-liter diesel engine rated at 174 hp and 339 lb.-ft.of torque or a 5.7-liter V-8 HEMI rated at 330 hp and 375 lb.-ft. of torque. Both engine choices will use a 5 speed automatic transmission. The vehicles also have a number of military-specific components, including tow loops that are rated for helicopter use, an air filter capable of running as long as five hours in zero visibility dust storms and remote-mounted batteries. Don't look for satellite navigation or leather seats, options are limited to paint color (Desert Sand or Military Green), a choice of a three door or five door body styles and air conditioning.

When Springs Break (Part 3)

Broken spring with 'spring splint' installed'The "Spring Saga" began with "Options for the height challengedwhich was a spring-over lift for my 1994 Jeep YJ.  As I was replacing a 4 inch spring lift, new springs were necessary.  The basic lift components were Rubicon Express and I opted for Rubicon Express springs which provided 1.5 inch of spring lift in addition to the spring-over lift.  I was able to remove the two inch body lift and still clear 35 inch tires.  

While the combination was a great performer on the articulation challenges of Ocotillo Wells SVRA, a major deficiency was soon apparent.  The Rubicon Express springs were not up to the stress of extreme flexing.  In Part 1 of “When springs break”, emergency repairs were made in order to get off the trail and into the shop for correct repairs.  Time was of importance as Tierra del Sol Desert Safari 47 was coming.  Part 2 of "When springs break" covered the install of a spring hanger reversal and new main leaf springs in the front to replace one broken and one bent spring.  I did make it to Desert Safari and some wheeling.  Final day, while driving slow on a washboard road, I heard an ominous snap.  This time, a rear main leaf spring snapped.  At least this time I had the proper “spring splint” kit to provide emergency repair.

When Springs Break (Part 2)

Shackle Reversal Spring Hanger

When Springs Break (Part 1) covered the basics of spring flex and potential problem that can arise.   Springs are a critical part of your suspension to provide for tire contact with the ground and keep the axle of your 4x4 centered while allowing movement.  So, what are solutions to reducing the chance of spring failure?  Certainly, moving to a coil spring suspension is one option to eliminate the flex issue with leaf springs.  Another option is to install to a shackle reversal.  That is a simpler and more cost effective option.

As noted in Part 1, leaf springs have a fixed point and a movable point.  For the front leaf springs, the fixed point is about mid-center of the vehicle.  When the front wheel encounters an obstacle, it is pushed back against the fixed point.  The force can cause undue stress on the spring and a potential for breaking near the rearward spring hanger: the fixed point.

When springs break...

There comes a time when venturing off road that leaf springs do fail.  Your day of 4x4 fun comes to an abrupt end.

Such an occurrence recently happened to me. Luckily, the main leaf spring did not completely break and I was able to make it home after some scrounging and rigging a "splint" to keep the spring from flexing and completing the break.

Time for a little break analysis.  For starters, the springs were new when installed with the spring-over lift in November and had seen 6 days of on the trail use.  Springs are designed to flex and should offer trouble free action over an extended life.  Spring failure can result from abnormal stress or metal weakness due to improper tempering.
