Air ride steering axle. This option was originally offered, but
later discontinued (was in the 359). The movement in the front axle
wore out bushings, tires, shocks etc.prematurely. There was also some difficulty in controlling
the air pressure to the airbags, so it either rode too choppy or too
soft. Recently, Pete brought back this option, after years of
working at smoothing it's bugs and glitches.
Remote locking systems. The early 379's had remote locking systems with an entire book of options available.
Air ride system. The 379 Peterbilt is the best riding truck available, with 3 different air-ride
systems, a system where the unit sits of 3 sets of air bags: there's air
ride on the axle, under the bunk and cab(Unibilt) and also in the
Improved turning radius. In fact, this feature was also superior to it's competition, too.
Aluminum cab and bunk. Just like the 359, the cab and bunk was still the
lightest on the market. The aluminum hood was very easy to tip,
Roomy under the hood. Just like the 359, the 379 Peterbilt kept the roomy area under the hood, so any engine and transmission combination would fit.
The 379 was always more expensive to buy than others on the market, but resale was then and still is now, 'tops' in the industry. In fact, even after the company has discontinued the production, the resale on a 379 Peterbilt, is even better now than ever!
