About CA Truck Parts, Inc.

Since 1987, CA Truck Parts has been a trusted supplier of diesel engines, transmissions, and heavy-duty truck parts for mechanics, truckers, fleet owners, and diesel repair professionals across the United States and internationally.

We began as a wholesale and export company, supplying container loads of diesel engines and truck parts to distributors and resellers worldwide. Many engines and components in the market originally came from CA Truck Parts — even if customers didn’t know it at the time. About eight years ago, we expanded into retail and began selling direct to consumers, making our inventory accessible to everyone online.

Today, we continue to grow our online inventory so customers can easily find diesel engines, transmissions, ECMs, and truck components available and ready to ship.

Quality Is Our Reputation

At CA Truck Parts, we believe reputation is everything.
That’s why our engines go through a strict process before being sold:

Engines are fully test-run
Internally inspected
Photographed from all angles
Verified for accuracy
If an engine does not meet our standards, it gets rebuilt

When you purchase from us, you’re not taking a risk — you know exactly what you’re getting.

Expert Knowledge That Sets Us Apart

Many truck owners and even repair shops are unsure which engine or component they need. That’s where we come in.

Our team uses Cummins, Caterpillar, and Allison databases along with decades of diesel experience to help customers select the correct engine or part the first time.

We don’t just sell parts — we help you make the right decision.

This expertise, combined with detailed engine photos, testing, and accurate information, is what separates CA Truck Parts from other suppliers.
