New Brochure Highlights Spicer® Heavy-Duty Tandem Drive Axles

May 24, 2007

KALAMAZOO, Mich., May 24, 2007 - A new six-page brochure from Dana Corporation’s Commercial Vehicle Systems group highlights the features and benefits of the Spicer® D170 and D190 series of heavy-duty, single-reduction tandem drive axles. The brochure and ordering information are available at

The brochure emphasizes the robust design features of the Spicer D170 and D190 axles by providing side-by-side comparisons with competitive axle designs. These features include wider faced hypoid gearing for greater strength, integrated systems design with 50 percent fewer parts than competitive designs for enhanced reliability, and a unitized ring gear bolting system with 20-millimeter bolts for maximum joint retention.

The brochure also describes the heavy-duty axle series’ larger tapered bearing systems; larger wheel differential gearing; and stronger, heat-treated steel differential cases – which result in enhanced performance, strength, durability, and reliability.

The brochure also includes information on several patented technologies that are used in the manufacturing of Spicer heavy-duty tandem axles. These include patented differential bearings that ensure precise bearing adjustments, patented on-demand lube pumps that lower operating temperatures and reduce fuel consumption, a patented driver-controlled differential lock option that promotes maximum traction, and patent-pending threaded input cages that eliminate leak paths and improve bearing adjustment.

Spicer D170 series heavy-duty tandem axles, with a broad ratio coverage of 3.07 to 7.17:1, are available for applications with gross axle weight ratings of 40,000, 46,000 and 50,000 pounds. Spicer D190 series heavy-duty tandem axles, with ratio coverage of 3.42 to 7.17:1, are available for applications with gross axle weight ratings up to 60,000 pounds.
