I would give Diesel Ops zero stars if…

I would give Diesel Ops zero stars if it were available. Please read the entire review because it contains valuable info. I spent hours online looking for a diesel supply house that had my turbo in stock. There website said in stock ships in 24 hours. After 8 days I tried calling 15 times. No one answers the phone. I sent 3 emails and 5 minutes before they closed for the day I got 2 emails back from different people. One said it was delivered which it wasn't, the other said it would ship from the manufacturer in about 10 days. Keep in mind, their website says "In Stock" ships in 24 hours. Finally the next day someone called me and told me the other two guys were new and didn't know what they were doing but she said she had one and could ship it out that day. 9 days after I placed the order. Meanwhile I had been searching again to find one and the manufacturer had them on sale for $150.00 less than Diesel Ops. I told her I would take hers if she matched the manufacturers price. I asked this because Diesel Ops has a "Price match guarantee" right on their website. She said the couldn't match the price because it was too cheap. Isn't that why someone would exercise a price match guarantee? I canceled my order telling her I believe their website is misleading and a fraud and their business practices are unethical and they didn't deserve my business. When I told her I was going to get online and give them a bad review she told me to "Go for it" I own my own business here in Minnesota and would never treat a customer like this. I asked to speak to the owner and she said "He wouldn't talk to me if all I was going to do was complain. I would never use these guys again and I certainly would not believe a thing on their website. Joe Toupal / New Brighton Minnesota

Ordered a tuner for my farm truck and installed it and my truck ran worse than before it was installed. Sent an email for a return label and got a return email that said they don't except returns on parts that had been installed. I'm out $500+ for a tuner that does not work... Will never order from them again. Be careful about ordering from them.

This is what I purchased, but what I got was a system they put together
from left over parts in a cat back box and install instructions for a 1983 firebird, and with a bent upper down pipe that made the system only useable as a cat back system. Called and emailed and got nowhere with them. Paid
for a turbo back and got screwed with a cat back. Be very careful doing
business with this company. Not honorable!

Great Company - Great Customer Service

I ordered a Bak Hard Rolling Tonne Cover from Diesel Ops.
Diesel Ops was very helpful through the whole purchase.
When i received the cover it did not fit as desired, Diesel Ops was very friendly and quick in helping resolve the problem.

They lost my package after I sent it to them for a refund because they sent me a defective tuner. So now I don't have no tuner, no refunds. they really don't care about customer service.

Michael,

The tuner you received was tested before it went out we did not ever receive the tuner to confirm the issue. We ask when people need tech support or a return to call us prior to doing so. When we spoke on the phone you were unable to provide me with a tracking number and you had stated that you did not insure the package so you were unable to get USPS to do this.We offered to replace this for you at a discounted rate but never heard back from you. Please let me know if there is anything else I can do for you.

Thank you

Diesel Ops customer service is TOP NOTCH. I would highly recommend purchasing from them to anyone. I had an issue with my original order and not only did they make it right, but they did it the first time without hesitation. Thank you Diesel Ops for being such a wonderful company to do business with and for offering outstanding world class customer service and product knowledge. Two thumbs up!

Kelly,

I am sorry that the test pipe you purchased did not work the way you wanted it to right off the bat. I show that we never heard from you about any issue so I would like the chance to look into this more and come to a resolution for us both. If you could reach out to me when you have some time I would like to do that for you. I want all of our customers happy with the products and the service that we provide.


Thank you

good service quick shipping but exhaust pipe dose not fit my model even though they said it would before I order it and still claim it does. I had to modify it to run the truck and now will be making custom one right. The wheel base measurements on kit do not my truck and my truck is stock.

Dave,

I am unaware of any fitment issues. These exhaust fit all the trucks besides ones that were a Cab and Chassis or considered Medium duty. I would be happy to help you with changing something out if needed but I can not help if we do not know about an issue.

Please feel free to reach out if you would like to get this taken care of
