Dana’s Commercial Vehicle Systems group has introduced the Dana Spicer D-2000F steer axle series for heavy-haul applications. The new axles are compatible with both air-disc and drum-style brakes, offer a 5-in. drop-beam option, and feature increased axle ratings up to 22,800 lb. The beam drop allows the truck manufacturer to lower the chassis, and that opens the door to several important benefits like improved cab entry and exit and additional passenger room in the cab. Other features, according to Dana: a patented power-rib beam design that saves weight while maintaining durability; a patented in-line, draw-key kingpin retention system with spring-washer tensioning helps to maintain good camber alignment while also improving durability and reliability; patented compressible inserts, seals, and threaded caps on the kingpin that improve contamination exclusion and grease retention; and tie rod ends with sealed boots and patented purge valves that also improve contamination exclusion. Two gross axle weight ratings (GAWR) are available: 20,000 lb for the D-2000F model, and 22,800 lb for the D-2200F.
