TOTALLY RAD: Western Star trucks now come with a larger radiator for improved cooling.
LOUISVILLE, Ky. –Western Star has fine-tuned several of its trucks and added some new options which were shown for the first time at the Mid-America Trucking Show.
The company’s 4900 SA day cab and sleeper cab models are now available with a 1,875 sq.-in. copper brass radiator, which Western Star officials claim is now the biggest radiator in the on-highway industry.
The larger rad was introduced to offer improved cooling in extreme-duty applications such as stationary pumping for oilfield services.
T. J. Reed, product manager, Western Star Trucks, showed the new radiator to Truck News at the show, and explained it can be packaged into existing hood envelopes without grille or hood modifications.
“The radiator’s copper brass and bolted steel tank construction results in an extremely durable product with heavy-duty chassis mountings,” he said. “The massive and efficient cooling package allows for maximum peak performance of 625 hp and 2,050 lb.-ft. of torque.”
Beginning in the fourth quarter of this year, Western Star customers will be able to spec’ their trucks with air disc brakes. The disc brakes will accommodate GCWs of up to 120,000 lbs, Reed said.
The disc brakes will be welcomed by heavy-haulers and premium on-highway fleets, the company announced.
The latest generation disc brakes are gaining in popularity because they offer improved stopping performance and require less maintenance.
Western Star has also upgraded its LowMax tractor. The LowMax can be ordered as either a day cab or with a sleeper.
Updates include an improved cooling package consisting of a 1,625 sq.-in. aluminum radiator and improved fan technology for better cooling.
The updated LowMax also handles better thanks to improvements to the front suspension and steering system, explained Reed. The distinctive LowMax is highlycustomizable, and features dual chrome six-inch stacks as well as other chrome and stainless steel accessories.
The company has also introduced a new Holland aluminum fifth wheel top plate which reduces weight by 100 lbs.
Holland officials say the new top plate is the lightest in the industry and does not require greasing. Holland has also integrated its Holland Hitch Sliding wheel with its Low-Weight Slider system, saving an additional 85 lbs. The new Holland offerings are available immediately for order on Western Star’s on-highway tractors.
