Powered by the 600HP DD16 Detroit engine and paired with an 18-speed Road Ranger gearbox, this truck delivers exceptional pulling power, torque, and drivability for demanding workloads. The 36” sleeper bunk offers premium driver comfort on the road, featuring a Coolabah lithium powered A/C system to ensure restful downtime, even when parked. Attention to detail sets this 48X apart — the fuel tanks have been painted Western Star red to match the chassis, replacing the usual polished alloy for a bold, uniform finish that’s easier to clean and maintain. Complementing the look and practicality, stainless steel rear mudguards provide a durable, low-maintenance finish that stays sharp with minimal effort. Tough, refined, and unmistakably Western Star — this 48X is built to work hard and look good doing it
