Machinery & Truck Parts30+ Years in the Diesel Business
Machinery & Truck Parts has been serving owner-operators, fleets, and repair shops for more than 30 years. What started as a local salvage and parts operation has grown into a trusted nationwide source for hard-to-find diesel components — but our approach hasn't changed: know the product, test what we sell, and stand behind it.
What We Specialize In
We focus exclusively on the heavy-duty diesel market. Our inventory is built around three things:
- Used diesel truck engines — CAT, Cummins, Detroit Diesel, International, Mack, and more
- Transmissions — manual and automatic units for commercial trucks
- Parts — fuel injectors, cylinder heads, turbochargers, engine blocks, ECMs, and other diesel components
Every part is inspected and tested before it ships, and warranties are included so you can buy with confidence.
A Top-Rated eBay Seller
We're a Top-Rated eBay seller with over 2,500 positive reviews from buyers across the country. That reputation comes from accurate listings, fair pricing, and fast nationwide shipping — and it's why so many customers come back to us for their next engine or part.
