Dana Corp.’s Commercial Vehicle Systems Division has introduced a new patent-pending tag axle specifically designed for 6 x 2 vehicle configurations requiring reduced weight in a variety of heavy-duty truck applications.

Weighing in at only 255 lbs., the Dana Spicer tag axle has the same external geometry as a standard drive axle to enable the use of conventional torque rod brackets and axle seats that are compatible with air-ride suspension systems. This is achieved without adding the complexity, cost, and weight associated with common tag axle configurations, the company says.

According to Patxi Garcia, engineering supervisor for Dana, the new tag axle provides operators with one of the lightest 6 x 2 packages in the commercial vehicle industry when specified with a Dana Spicer 23,000 lbs., or 21,000 GAWR single-reduction, single-drive axle.

Designated as axle model number R22BS and rated up to 22,000 lbs., the tag axle housing profile and box size are common with the Dana Spicer DS404 tandem drive axle for 6 x 4 configurations. The R22BS also includes standard “R” series spindles, which are compatible with standard truck wheel-ends or the Dana Spicer LMSTM hubs to help ensure consistent, reliable road service.
