LOUISVILLE, Ky. — A new generation of heavy-duty drive axle gearing that reduces noise, vibration, and harshness has been introduced by Roadranger — drivetrain, chassis and safety components venture from Dana and Eaton Corp.

GenTech hypoid gearing, now available as a production shipment option, provides automotive level, best-in-class (NVH), for medium- and heavy-duty vehicle applications that require increased torque capacity and maximum durability.

“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 of 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 truck 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.
