A cooling package for 2002 EGR engines is said to improve cooling efficiency by 35%, while reducing the system's weight by 80 lb. The new system saves space by putting the charge-air cooler on top of the radiator rather than in front of it.
For vocational fleets, Peterbilt unveiled a redesigned hood and set-back front axle package for its Model 357 in both straight truck and tractor configurations. The increased slope of the hood expands forward visibility while the set-back front axle increases turning radius. As part of an effort to get products to vocational customers more quickly, Peterbilt has formed a partnership with Heil Environmental Industries to speed assembly of trucks and dump bodies.
Allison 2000 and 2400 Series automatic transmissions are now optional on Peterbilt's medium-duty Model 330 trucks. The 330 chassis also has a new auxiliary helper spring rated at 4,500 lb. Finally, axle-mounted parking brakes are now an option on 330 units spec'd with hydraulic brakes.
