8000-lb Steer Axles Join Roadranger System

Dana Corp. introduced two new 8000-pound steer axles for the Roadranger drivetrain system: Dana Spicer D-800F and D-800W. 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.
