GKN Produces Countertrack(TM) Propshafts for Chrysler Group


AUBURN HILLS, Mich., Dec. 19 -- GKN Driveline's new countertrack(TM) PX propshaft technology that provides weight-savings and fuel-efficiency benefits will be added next year as a running change to some versions of the Chrysler Group's 2007 model-year Dodge Ram and Dakota pickup trucks and Durango sport-utility vehicle.

GKN Driveline's countertrack(TM) is the first major breakthrough in fixed, constant velocity ball-joint (CVJ) technology for the auto industry in 70 years.

Because of its unique track design, GKN Driveline's countertrack(TM) system balances internal forces within a joint to improve operating efficiency by reducing energy losses due to heat and friction. Another design feature allows engineers to reduce overall package size.

While exceeding the durability requirements of current CVJs, the technology provides car makers with the potential to achieve:

o A 10 percent smaller package size for a given power rating,
o A 25 percent reduction in weight over current CVJs, and
o More than a 30 percent increase in efficiency.

The countertrack(TM) PX propshafts for Dodge will be assembled at the company's Roxboro, N.C., plant from components produced at a GKN Driveline facility in Spain. The company will ramp-up production on the new propshafts during the first quarter of 2007. The completed units will be shipped to Chrysler Group plants in Newark, Del.; Warren, Mich., and St. Louis, Mo.

"GKN Driveline's countertrack(TM) technology will provide Dodge with significant improvements in durability and operational temperatures by reducing friction in a package size that is smaller and lighter than previous propshaft designs," said Rob Rickell, director of engineering for GKN Driveline's global driveshaft business.

In addition to propshaft applications, GKN Driveline has developed countertrack(TM) CVJs for sideshaft applications, named the SX joint. Originating as a concept at the company's Advanced Product Development Group, the SX joint was created in response to consumer trends toward increasing power ratings of multiple engines, while maintaining common suspension and platform dimensions.

GKN Driveline countertrack(TM) PX and SX joint designs have been patented in many countries and other worldwide rights are pending.

GKN Driveline is a global enterprise with 21,000 people working at more than 40 locations in over 30 countries. The company recorded sales of $3.8 billion in 2005. Recognized as the auto industry's leader in the design and production of driveline components, GKN Driveline provides driveline solutions for the smallest front-wheel-drive vehicles up to the most sophisticated four- wheel-drive models. The company has a commanding share of the global market for CVJ (constant velocity joint) sideshafts and also is a leading global producer of all-wheel-drive PTUs (power transfer units) and torque management devices.
