Peterbilt 379 guide with specs, used prices by year and resale value

Along the highways and byways of North America, one of the most common – and most popular – semi trucks you’ll see hauling freight across the continent is the classic Peterbilt 379. This iconic transport truck – with its long rectangular front end, squared-off radiator grille, tall double exhaust stacks and a driver’s cab that often looks like it has a furrowed brow – looks like it means business.

The Peterbilt 379 is a long-hood semi truck that Peterbilt stopped building in 2007, and used ones still sell for roughly US$20,000 to well over US$100,000 thanks to their durability, easy maintenance and classic styling. Below, we cover its specs, cab options, price by year and the model that replaced it.

Is the Peterbilt 379 still a reliable truck?

Yes. A well-maintained Peterbilt 379 can run 750,000 miles without a rebuild, which is why truckers still trust it years after production ended in 2007. Used Peterbilt 379s are still counted as trusted workhorses that were built to last. But there’s more than just reliability behind their status as kings of the road. They’re also highly customizable, with plenty of aftermarket parts available – from lights and mirrors to fenders and panels and more. You’ll see this truck in everything from classic stock look to fully tricked out.

Let’s take a closer look at some of the advantages a used Peterbilt 379 truck tractor still offers.

Why is the Peterbilt 379 so popular?

One of the big factors in this semi truck’s popularity is its ability to keep on truckin’, for miles and miles. It was – and still is – easy to maintain and repair, and a well-maintained Peterbilt 379 semi truck can run 750,000 miles without a rebuild, and can get up to 1,000,000 miles and more.

What are the Peterbilt 379 specs?

The Peterbilt 379 came with a wide choice of Caterpillar, Cummins and Detroit Diesel engines, in tandem or tri-axle configurations, under its signature long hood. That engine and transmission versatility is part of the reason for its distinctive long hood and front end. Buyers could choose from Caterpillar 3176, C-11, C-12, C-13, C-15, C-16 and the 3406-(B,C,E,P and EWS); Cummins Big Cam NTC, N-14, ISM, ISX, ISMe5, ISXe5, and Signature 600 engines; as well as Detroit Diesel 60 series. The truck was also available in tandem and tri-axle configurations.

Fuel-efficiency also put the Peterbilt 379 at the head of the pack, with the aluminum body reducing weight, which in turn reduced fuel consumption.

What cab and sleeper options does the 379 have?

The 379 offers a wide variety of cab and sleeper options, making it a favorite of long haul truckers who rely on it as their “home on the road”. The truck is available as a day cab or with a full range of fully-kitted out and customizable sleepers from 36” up to 144” ARI.
