About Peterbilt Parts Depot
Specialist Heavy-Duty Truck Parts,
Built for the Road
When your Peterbilt is your livelihood, the last thing you need is a parts supplier who treats your Class 8 truck like just another line item. Peterbilt Parts Depot was built from the ground up to serve one customer: the serious trucking professional who needs the right part, sourced correctly, and shipped fast. We are not a generalist retailer. We are Peterbilt specialists — and that distinction matters every time you place an order.
A Family-Owned Business Built Around Peterbilt Trucks
Our family has been in and around commercial trucking for decades. We grew up watching owner-operators spend hours on the phone chasing down parts that turned out to be wrong fitment sourced from suppliers who had never seen the inside of a PACCAR cab in their lives. When the internet made it possible to build a better option, we did exactly that.
Peterbilt Parts Depot was founded in Houston, TX 77024, out of a genuine frustration: too many online parts sites were selling Peterbilt components with generic catalog data, mismatched fitment information, and zero product expertise to back it up. The trucking community deserved something better a source staffed by people who could tell a 389 from a 579 at a glance and understand exactly why that difference matters when you're ordering a cab mount or an air filter housing.
That is the business we built, and it is the business we run today family-owned, Peterbilt-focused, and accountable to every customer who puts their trust in us.
Every Major Peterbilt Model
We carry parts for every major Peterbilt model in active commercial service, and our team understands the distinctions that separate one platform from another. The 389 and 579 do not share the same cab structure — parts are not cross-compatible between them — and that kind of model-level knowledge is the difference between a clean repair and a costly return.
Engine coverage spans PACCAR MX-13 and MX-11 powerplants, Cummins ISX15 and ISX12 variants, and all associated drivetrain components including Fuller Advantage series transmissions, Meritor rear axles, and Eaton clutch systems. Not sure which part fits your specific truck, year, and configuration? Our parts advisors can confirm compatibility before you order.

Sourced From Trusted Suppliers
Our OEM parts are sourced through certified Peterbilt and PACCAR supply channels the same supply chain that dealers draw from which means you receive manufacturer-specified components with the documentation to back them up.
On the aftermarket side, we apply a strict vetting process. Not every aftermarket brand earns a place in our catalog. We evaluate every aftermarket line against Class 8 commercial durability standards, because a part that holds up on a passenger car has no business being installed on a truck running 150,000 miles a year under load. We will never compromise on part quality to protect a margin — that is the kind of shortcut that costs fleet managers downtime they cannot afford and owner-operators money they cannot recover.
Every part in our catalog has been evaluated for fitment, durability, and application accuracy before it goes live.
Why Owner-Operators and Fleet Managers Choose Us
We do not sell refrigerator parts one day and heavy-duty diesel components the next Peterbilt is all we do, and that focus produces a depth of inventory and expertise that generalist retailers simply cannot match.
Owner-operators choose Peterbilt Parts Depot because they get the right part the first time, without the guesswork and without the costly returns that come from bad fitment data.
