Dana Corp.
Dana Corporation’s Commercial Vehicle Systems announced the introduction of the new Dana Spicer D-800F and D-800W steer axles to the Roadranger Drivetrain System. The company says the new 8000-pound axle models feature improvements in basic steering geometry to enhance vehicle steering under a variety of driving conditions and provide an option for wide-track applications.

The D-800F replaces the I-80SG steer axle and maintains the proven kingpin, bushings, bearings, and seals of the I-80SG. The D-800W steer axle features a 1-inch wider beam than the D-800F, which results in a wider track for increased maneuverability.

The increased kingpin angle improves high turn angle steering returnability, and a reduced scrub radius improves steering stability. The engineered powdered metal kingpin cap design seals the bushing cavity, ensuring proper re-lubrication. Bolted-on kingpin caps ease serviceability and provide for auxiliary attachment. Threaded inner and outer drawkeys also improve serviceability. An over-sized tie-rod assembly improves durability and results in common service parts, the company says.
