Auto repair in the United States is split between independent shops, dealership service departments and national chains. Independents handle most routine work (oil changes, brakes, tune-ups, check-engine diagnostics) at lower labor rates and often specialize in one make or in imports; dealers keep factory tools, software and warranty authority; chains sell speed and standard pricing on maintenance items. Most shops charge a diagnostic fee, credited toward the repair if you go ahead, and quote parts and labor separately. Certification matters: look for ASE-certified technicians and, in many states, a state repair license posted at the counter. Written estimates are required by law in most states before work begins, and you are entitled to your old parts if you ask.
Hours are published for 5 days a week. Typical hours are 8 amβ5 pm. It is closed on Saturday, Sunday. Hours in the United States do change around federal holidays and long weekends, so a quick call before a special trip is sensible. The listed phone number is (210) 341-8183. Many businesses also reply to text messages on the same number if it is a cell phone. More information is available on its website, duffindiesel.com.

I don't even know where to start, so I will begin with the experience of Donald Duffin. The man knows his stuff! I had them do the machine work on my Cummins 6.7 build, which I was going to do for a minimum of 1,000hp. He was invaluable and knowledgeable and had all sorts of tips and tricks for when it came time for me to assemble it. Regarding the machine work, boy, the crew at Duffin Diesel is at the next level; they are craftsmen! The work on my block was perfect, and the engine was precisely to spec. The work they did line boring the cam journals for me to run bearings on all of them was also top-notch. Fast forward to the assembly, and the engine went together amazingly and is precisely what I was hoping for and dreaming of. If you are looking for a shop that is top-notch and skilled artisans, this is the place. There is a reason that Zach Hamilton, who is over at Hamilton Cams, recommended Duffin Diesel to me. They are the real deal and are what you want in a machine shop!

I went today to find out if they could clean and resurface some parts for a car I'm building . I found them to be very knowledgeable and helpful . I have read the reviews and was concerned about them being rude and unprofessional. They were more than helpful with my experience with them . I have a feeling they are so busy and great at what they do they probably get overwhelmed with work . When that happens to me I would probably be short with people . Over all my experience was great .

Prices are very fair and workmanship is exceptional. The guys are very experienced. I've had several parts cleaned, crank checked and ground, rods worked, and now I'm taking all the rotating parts in to get em balanced.
