The Peterbilt 388 and 389 are difficult to differentiate from
one and other. The looks are very similar, but there are subtle difference
outside of the length of hood. The most noticeable location to spot the
difference is at the back of the hood where the 388 will have more skin showing
above the panel seam and the row of huck rivets than a 389.
The 388 is a 123" Bumper to Back of Cab aluminum hood
premium conventional. The 388 cab sits higher off the frame rail than the
389. 388 slope is more pronounced than that of the longer 389. The
difference is quite noticeable on 388 at the rear of the hood where the
difference in height from the panel seam and huck rivets is much taller on 388.
The 388 replaced the 379-119"
Both 388 and 389 share the same crown, grille, headlamps,
fenders, front and rear fender brackets, cooling components, engine and
drivetrain options and stepboard skirts.
