Mopar Underground Design Team at Moab

Auburn Hills, Mich. – Mopar® and the Mopar Underground team showcased their customized Jeep® vehicles and Dodge trucks at Moab Jeep Safari 2008 in March.

“Jeep engineering has been coming to Moab for years. Mopar is at Moab to test, evaluate and prove the authenticity of our Mopar Performance Parts for Jeep vehicles and Dodge trucks on the most grueling off-road trails in Moab,” said Simon Boag, President – Service & Parts/Mopar, Chrysler LLC. Mopar is Chrysler LLC’s original equipment parts manufacturer and supplier.

Boag added, “We wanted our core off-road customers to talk about their vehicle usage so we can address their unmet needs and identify emerging product trends to better support their off-road adventures. Mopar prepped several vehicles for Moab Jeep Safari to gauge consumer feedback and reaction.”

Overseen by Ralph Gilles, Vice President of Jeep/Truck & CFM Design, Chrysler LLC, the Mopar Underground design team has been customizing production vehicles since its creation in 2002. The Mopar Underground design team creates vehicle concepts meant to develop performance parts, accessories and customization as well as new vehicle concepts. In fact, the first-generation SRT4 was born from this team’s style initiative.

“Our diverse team which changes frequently has been developing SEMA concepts for more than five years. It’s the usual ‘enthusiast’ suspects from our union shops [plastic, paint, metal and wood], Product Design Office, SRT and Mopar Performance Parts and engineering,” said Gilles.

“We try to push the boundaries of conventional thinking—customizing with no limits to creative expression and freedom, just the power to imagine. We want to build customized concept vehicles that flex the potential in our platforms, show that Chrysler, Jeep and Dodge vehicles are indeed designed for customization and keep the Mopar spirit and passion alive,” said Gilles.

Vehicle Customization Industry

  • The 2007 Jeep Wrangler was named one of the most accessory-friendly vehicles by SEMA members
  • According to a Foresight Research report conducted last year [commissioned by SEMA's Research and Information Center], more than 1,700 full-size truck owners revealed that 50 percent had spent or planned to spend $500 or more on accessories—with a high of 63 percent for Dodge Ram owners (most likely to accessorize). And 20 percent of that group said they bought their trucks at a particular dealership because of the availability of accessories

Jeep Wrangler Rubicon KingJeep® Wrangler “Rubicon® King”
An amplification of Jeep’s most capable off-road machine. Taking full advantage of the 4:1 ratio Rock-Trac transfer case and Tru-Lok-equipped Dana 44 axles, the JK Rubicon King utilizes massive BF Goodrich 37 x 12.50-17 TA Krawler tires mounted on Hutchinson beadlock wheels from Mopar. Superlift Suspension provided the 4-in. lift for extra ground clearance. Warn-supplied the new 9.0 RC Rock Crawling Winch. Featuring a six-speed transmission, power is provided by the 3.8-liter V-6 engine under the hood.

Custom features include relocation of the spare tire where the back seat used to reside, fender flares and grille trimmed for extreme clearance, trick lighting, military spec tow shackles and radio delete plate. Other features include American Expedition vehicle’s new heat-reduction hood and rear corner guards.

The “JK Rubicon King” premiered at the 2006 SEMA Show and traversed the trails at Moab Jeep Safari 2007.

Jeep® Wrangler JT
Built from the military version of the all new Jeep Wrangler, the Jeep Wrangler JT showcases just how flexible this new platform can be. Revealed at the Moab Jeep Safari 2007, the JT dominated the steep climbs and descents on the slopes of the Hell’s Revenge trail. Its 4×4 capability was established as it negotiated the slick hot tubs and waterfalls – at times, almost completely vertical to the ground.

Beginning with the new 116-in. wheelbase platform for the Wrangler Unlimited, the design team managed to create a very nimble, trail-savvy Jeep with a 5-ft. pickup bed and an easy-to-handle removable hardtop. Power is provided by its 3.8-liter V-6 engine.

Off-road enhancements include:

  • 4-in. suspension lift provided by Superlift
  • 35-in. BF Goodrich Mud Terrain tires
  • Rear bumper and tire carrier from Mopar
  • Front bumper from Mopar
  • Warn 9500ti winch

The Wrangler JT is painted Hearing Aid Beige. The JK JT premiered at Moab Jeep Safari 2007 and was shown at the 2007 SEMA Show.

Jeep® Grand Cherokee “Grand Canyon”
The “Grand Canyon” features 33-inch tires and a 4-in. lift. Power comes from a 3.0-liter V-6 CRD engine under the hood. The “Grand Canyon” premiered at Moab Jeep Safari 2006.

Plenty of power and traction comes with the 3.0-liter CRD diesel engine under the hood that pushes 230 horsepower and 390 lb.-ft. of torque. There are Tru-Lok-equipped Dana 44 axles underneath. Performance suspension lift allows clearance for 35-inch BFG Mud Terrain tires mounted on custom 18-inch aluminum wheels supplied by Taneisya.

The exterior features a Warn 9.5ti winch mounted on an American Expedition front bumper. A full-size spare is carried by a rear bumper from Mopar Performance Parts. Sprayed in Rolex Silver paint, it looks like a billion bucks.

Jeep® Wrangler “All-access”
The interior of the Jeep Wrangler All-access has been upgraded with premium materials and paint. To give it “trail and off-road” credibility, the designers vamped it up with Mopar Performance Parts including a Rubicon Express 4-in. suspension lift, front and rear bumper with tire carrier, rock rails, cold air intake and a Warn 9500ti winch. American Expedition Vehicles supplied its new Pintler sheels.

Power comes from the 3.8-liter V-6 engine. Painted “Surf Blue,” the “All-access” also features 35-in. BFG Mud Terrain tires. The “All-access” premiered at the 2007 SEMA Show.

Jeep Wrangler J8 SargeJeep® Wrangler “J8 Sarge”
The Jeep Wrangler “J8 Sarge” is a military version of the new JK platform built as a non-combat military support vehicle. Built from the 116-inch wheelbase version, the “J8 Sarge” is offered in either two-door or four-door configurations. Special J8-only structural upgrades in the body and chassis combine to increase the GVWR rating to 7,400 pounds.

The platform can be configured as a light-troop carrier, ambulance or cargo truck. Other notable features include the Dana 60 rear axle mounted on leaf springs, larger front-disc brakes and exclusive J8-only 17 x 8 steel wheels with a larger 5 x 5.5-inch bolt pattern.

70 Years of Mopar
When Chrysler bought Dodge in 1928, the need for a dedicated parts manufacturer, supplier and distribution system to support the growing enterprise led to the formation of the Chrysler Motor Parts Corporation (CMPC) in 1929.

Originally used in the 1920s, Mopar (a simple contraction of the words MOtor and PARts) was trademarked for a line of antifreeze products in 1937. It was also widely used as a moniker for the CMPC. The Mopar brand made its mark in the 1960s – the muscle car era. The Chrysler Corporation built race-ready Dodge and Plymouth “package cars” equipped with special high-performance parts. Mopar carried a line of “Special Parts” for super stock drag racers and developed its racing parts division called Mopar Performance Parts to enhance speed and handling for both road and racing use.

Today, Chrysler’s Global Service and Parts division is responsible for the manufacturing and distribution of nearly 250,000 authentic Mopar replacement parts, components and accessories for Chrysler, Jeep and Dodge vehicles sold around the world. To assure quality, reliability and durability, all Mopar parts and accessories are designed in strict adherence to Chrysler engineering standards.
