When something went wrong
Most suppliers hide this. We don't. How a company handles mistakes tells you everything about who they really are.

"These guys are great. I had my rebuild kit in one day! I got a follow up phone call to check that I got my shipment and it was correct. Thanks Diesel Pro Power!"

"I typed the wrong address. The team was super helpful and patient — sent out another order, tracked down the missing packages, refunded accordingly. All with a cheerful, kind approach."

"They called before shipping to check everything was right. They caught that I'd ordered a 12v gauge instead of 24v — and fixed it before it left the warehouse."

They answer the phone
Every review about this sounds surprised. That says something about the industry — and about Diesel Pro.

"Dylan is the most customer-concerned employee that I have had the pleasure to deal with in a very long time. His genuine concern showed with his phone calls making sure that all of our concerns were met. An absolute pleasure to deal with."

"From start to finish it was nothing but positive vibes. Packaging was clean, safe, and professionally put together. Shipping was quick and even a follow up call after delivery to make sure all was A-OK. It's hard to find good customer service today. Diesel Pro has gained another satisfied customer. It's nice to know I have a source for parts just a phone call away."

We visited Captain David of the Reward Fishing Fleet and filmed him starting his Detroit Diesel 8V71 engines. These engines run every day. That's why he uses Diesel Pro.

"Luis and Diesel Pro Power are the BEST. Their parts are in some cases better than OEM. Service from Luis is like dealing with an old friend and he's available at the drop of a hat. This is the go-to place for my Detroits as well as any other engine they carry."
