About SATX Parts & Supply

Who we are

SATX Parts & Supply, LLC is a family-run parts business based in San Antonio, Texas. We specialize in new-old-stock (NOS) and surplus heavy-equipment parts — the hard-to-find part numbers that keep older machines running long after a dealer tells you a part is "no longer available." Much of what we carry is genuine surplus that has never been listed online anywhere else, so if you have been hunting a discontinued number, there is a real chance it is sitting on our shelf right now.

We are not a big-box parts counter. We are a small operation that knows its inventory, answers the phone, and takes the time to cross-reference a number instead of just saying no. If you send us a part number, a real person checks the shelf.

What we stock

Our inventory runs deep across several categories of heavy-equipment parts:

We carry parts for Euclid-Hitachi, Cummins, Perkins, Isuzu, Caterpillar-referenced, and other heavy-equipment brands. See our brand-specific pages for details: Perkins parts, Cummins parts, and Euclid-Hitachi rigid hauler parts.

Grader blades, in bulk

For counties, municipalities, and road departments, we also source motor-grader cutting edges, end bits, and blades in bulk quantities. Grader blades are quoted and sourced to order rather than kept as walk-in shelf stock, so reach out with your specifications and quantity and we will get you a quote. See our grader blades page for more detail, or we respond to county bids and quote requests directly — a W-9 is available on request.

Who we serve

We work with contractors, owner-operators, repair shops, fleet maintenance crews, aggregate and quarry operators, and government road departments — across Texas and nationwide. Whether you are keeping a single machine running or managing a fleet, we ship parts anywhere in the US from our San Antonio warehouse.

How ordering works

1. Send us the part number — from our listing or off your old part — and we will confirm fitment before you buy.
2. Tell us your ZIP code and we will get you a shipping quote. Smaller parts typically ship UPS; larger items go by freight, quoted after purchase.
3. Buy with confidence: purchases made through our eBay store include 30-day returns.

Have a part number that is not listed on our parts catalog or on our eBay store yet? Just ask. We have thousands of parts on the shelf that have not made it online, and we are glad to check stock and cross-reference a number for you. And if you have surplus heavy-equipment parts sitting around, we buy inventory too — see sell us your surplus.
