Dana Corporation's Commercial Vehicle Systems introduces the new Dana Spicer® D-800F and D-800W steer axles. The new axles 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 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 in.) wider beam than the D-800F, which results in a wider track for increased maneuverability.
