Peterbilt Motors has expanded its vocational Model 357 with two new models: a 357-115 with a 115-inch BBC, four inches shorter than standard; and a 357 Heavy Haul with extra cooling capacity and Big Power engines. Both have a setback front axle for optimum weight distribution in many states and greater maneuverability than the axle-forward version.
The 357-115's steer axle is 68.5 inches from the back of the cab so it can shoulder a higher share of the payload, which is useful to mixers, dumpers, loggers and trash haulers. The axle position also allows a tight wheel cut and reduces the turning radius.
Additionally, the new configuration features a sloped hood and a lowered crown and grille that improve "groundstrike" (the driver's ability to see the ground or pavement ahead). Side visibility is also increased by about 17 percent from a redesigned door with a lower window beltline.
FEPTO (front engine power take-off) provisions are standard, as are a stationary grille and heavy-duty frame rail extensions for secure, stable mounting of auxiliary equipment such as a hydraulic pump to power a mixer barrel. FEPTO-driven equipment is typically easier to service than back-of-cab mounted equipment. For additional strength and rigidity, optional frame rail liners are available.
The 357 Heavy Haul has a 1,440-square-inch radiator core, which can cool engines like Caterpillar's 625-hp C15 and other high-power diesels. It is designed for pulling lowboy and equipment trailers and for dump, snowplowing, logging, stationary oil field and well drilling.
The 357 Heavy Haul has a 119-inch BBC and a setback front axle. It is available in both truck and tractor configurations. It features a stationary grille that allows the hood to open without interfering with auxiliary equipment mounted to the front bumper. A wide range of heavy-duty options, like extra-heavy-duty frame rails and liners, suspensions and pusher or tag axles, meet individual customer needs.
Peterbilt dealers are now taking orders for the 357-115 and 357 Heavy Haul. They go into production this summer.
