Make room for Peter

Making their way onto the scene in 1948, Peterbilt Trucks have been one of the best all-around brands on our nation's highways since. This American-built powerhouse can be seen honking their horns for adoring fans on any number of roadways. Peterbilt makes some of the most reliable trucks out there. But if they do happen to break down, they're an absolute pain to shop for. It's a major expense to shop a new engine or transmission for your truck. So, to save on the outrageous cost, a lot of people pick up used Peterbilt parts. Buying a used part from any supplier just won't do. And since some companies are only after your hard-earned money, you really don't know who to trust. At Automotix, our quality, used auto engines and transmissions are the best that money can buy.

Peterbilt engines and transmissions are huge, and they're also hard to find. This is why Automotix makes sure to keep them in stock. We can locate the used Peterbilt engine or transmission you need and get it out to you in a hurry. We have engines like the 12.9 Liter PACCAR and the 388 readily available. For those big, 10-speed, 13-speed and 18-speed used transmissions; Automotix is the cheapest place to shop. We guarantee that we can match you with the used Peterbilt engine or transmission you need.

We carry a wide selection of parts just for Peterbilt. No matter what size you're looking for, Class 5 through 8, we carry the parts you need. Just like anything you buy from us, your part automatically comes with a standard 1-year warranty. We're the only supplier around who can offer that to you. We guarantee that you Peterbilt owners will be satisfied with the part. And to emphasize even more just how much customer satisfaction means to us, we also offer a 90-day price match guarantee. If you're able to find the same used engine or transmission with the same warranty and mileage, we'll automatically match the competing price.

At Automotix, we deal directly with you, and that's what makes us stand out from all the rest. With over 200 salvage yards throughout the country, we can completely eliminate any third party and ship directly to your doorstep.

We can process any order quickly, no matter what size, and your product will be shipped out to you immediately. By purchasing directly from the source which carries your part, you get a cost-effective, risk-free business transaction every time.

Few trucks are as popular as Peterbilt. And it's because of their popularity that your odds of finding the used engine or transmission you're looking for are greatly increased. But if you can't find your particular make or model, don't worry. All you have to do is contact us and tell us the exact make and model that you need. After that, we'll quickly find the part for you, no problem. With the increasingly high demand for these parts, we can't always keep our site totally up-to-the-minute. But if you need a particular part, we will locate it for you and offer you our same 1-year warranty! No other supplier in the entire industry can offer you anything close to what we do. If your Peterbilt needs some quality care, then Automotix is the only stop you'll need to make on the road to recovery.
