KALAMAZOO, Mich. — Dana Corp.’s Commercial Vehicle Systems has introduced the new Dana Spicer D-800F and D-800W steer axles.

The new 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, according to the company.

“The product advancements featured in these steer axles will improve driver satisfaction through reduced driver fatigue, enhanced performance, and improved productivity,” says Mark Davis, product manager of steer axles with Commercial Vehicle Systems.

The Dana Spicer 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 25 mm (1 inch) wider beam than the D-800F, which results in a wider track for increased maneuverability.

Both new steer axle models improve steering and maneuverability through several new product enhancements. 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.
