KALAMAZOO, Mich., March 24, 2006 -- Dana Corporation’s Commercial Vehicle Systems group has announced that GenTech™, a new generation of heavy-duty drive axle gearing, is now available as a production shipment option. GenTech hypoid gearing provides automotive level, best-in-class reductions in noise, vibration, and harshness (NVH), for medium- and heavy-duty vehicle applications that require increased torque capacity and maximum durability. GenTech gearing also is available for school buses, motor coaches, and recreational vehicles.

“Dana’s GenTech gearing is a proprietary system utilizing the latest computer aided design methods, premium manufacturing processes, tightly controlled heat-treat and material specifications, and advanced in-line testing,” said Leo Wenstrup, senior product manager, drive axles for Dana. “We have optimized the tooth geometry and contact pattern by leveraging Dana’s experience in automotive gear technology through the use of premium processes, advanced gear tooth cutting machinery and tools, and new manufacturing equipment. The result is superbly matched gear tooth positions.”

He added that the automotive-quality hypoid axle gearing results in substantially quieter and smoother axle operation, while still maintaining the strength and durability required for medium- and heavy-duty commercial vehicle applications.

GenTech gearing is initially available in Dana’s newest Spicer® S110 and S130 single drive axles with gross axle weight ratings of up to 16,500 pounds. Additional axle models will follow later in 2006.

" Dana’s GenTech axle gearing technology demonstrates Dana’s commitment to provide our customers with the innovative and durable products they need,” added Wenstrup. "Dana’s extensive experience and technology in the automotive axle and systems business allows us to effectively apply appropriate products and techniques for the benefit of our commercial vehicle and off-highway customers.”
