Western Star Trucks’ 4900 FA model series, geared toward the construction and severe-duty applications such as West Coast mixers and super dump applications, has the new set-forward 109-inch BBC twin steer featuring a three degree wheel cut improvement over previous designs, which offers greater maneuverability for off-road applications. Not only will it allow for better off-road capabilities and a tighter turning radius, the factory installed BBC option is more cost efficient when compared to an aftermarket conversion. The 4900 FA 109-inch twin steer is equipped with a 450 hp, 12.8L MBE 4000 engine, Eaton Fuller 11-speed transmission and Meritor Tandem 40,000 lb front axles and 46,000 lb rear axles. In addition, the 4900 FA twin steer features shackled springs, rather than slipper springs, for a 30 percent ride improvement without compromising load ratings.
