2012 RAM R2500

This kit made an improved performance with the truck quite obvious. The installation was clearly stated and depicted. My technicians only issue was that there was NO instructions included with the product. He went onto the site and downloaded over 20 pages on the instructions and manual which I provided to the customer. For the cost of the kit,at least the installation guide could have been included. He had to take time to get this from your website,and you know,a technicians time is VALUABLE.

Great customer service

I had a little trouble ordering my parts, DieselOps called me and helped me get everything I wanted. I will definitely be going through them on my next order.

not impressed

I got the wrong turbo I couldn't tell in the picture but this one is for a later 2004 f350 which has the different pedastool so now I have to get that other one. It's not that I want or need a sinister sticker or diesel ops sticker or shirt or receipt or anything but you figure when you spend 1600$ on a turbo you'd at least get a sticker and a receipt

Jacob,

I am sorry you order the wrong turbo, we gladly will take care of that for you and will gladly get this handled. I see that you ordered for the 04 truck but as you said you did order the wrong one. As for the sticker and receipt, the receipt was emailed to you when you placed the order and was then emailed again when it shipped. We do not put them in the box. The sticker however due to you being so far from us we shipped from outside our Michigan warehouse and they do not have stickers we assumed it was more important to have it to you in a timely manner.

Please let me know if there is anything else I can do to help or get taken care of for you.


Thank you

Didn't recieve shipment...

Just hope nothing goes wrong with your shipment or ordering process as I've called and emailed this company over the past couple weeks and still no head way as far as where my package is. I was supposed to recieve it about a month ago. Customer service is defintely lacking here. Very unhappy.

Hello Cody,

I understand the frustration here however when something is stolen after it is delivered sometimes the resolution is slow. We do our best to get things handled quickly but like I stated it is not always the quickest because the shipping company has to do a investigation prior to releasing the credit to us from the insurance. I am sorry that you are having trouble with this and I am sorry that you are feeling like the resolution to this is slow but having only jumped in on this Monday (3 days ago) I am doing my best to make it happen as quickly as possible.

Thank you and I look forward to getting this taken care of and seeing you receive the product like you planned on.

Sales staff is second to none!

I worked directly with Corey to get all of the parts I needed for my 2011 Ram. He went above and beyond to answer my questions, explain my options, and created the best package deal. I had an issue outside of his control and he resolved it immediately. Hands down, one of the best customer service experiences I have ever had!

Great company to buy from.

I purchased a kit for my powerstroke with h&s mini maxx. I couldn't install the tuner tof my truck so I tried to call hs and they are out of business. So I called dieselops.com, someone said they could help me and would send an email with instructions. I waited 2 days for the email before calling another company who sells these tuners, who helped me over the phone within 10 minutes. So long story short, they sold me something at a great price, and didn't offer any troubleshooting help. Won't be using them as a supplier anymore.

Hello Mike,


I am sorry you had issues with that, the Mini Max tuners come with the instructions in the box as well if you look at the invoice that you were sent we email over install instructions for every product we sell. This is to prevent issues such as this and make it easier for my customers as well as shops who are installing something! However I would be glad to help you out here and If you have any other questions I would be glad to get them taken care of.

Please let me know if there is anything else you need I look forward to hearing from you

Thank you

Excellent customer service

I called several diesel stores around including Dales super store, alligator performance, and Xtreme diesel. Diesel ops were the only ones to seem like they cared to answer all my questions I had. Nick was extremely helpful with the ordering and excellent customer service.They also are the best price around and all my stuff was at my house in a couple of days. I recommend diesel ops for all your diesel needs. Will do business with them for now on.

Great Company!

The salesman, Chris, was very helpful and knew exactly what I was wanting to help the performance of my truck. Parts fit perfectly and I'm very pleased with the performance of my truck. Diesel Ops prices were better than anyone else's, and the fact that they are pro military and law enforcement made me proud to do business with them!

I was honestly going to just order everything on line but noticed the price match on the home page. Let me just say, don't be lazy and click. Pick up he phone and call! They will get you their best deals if you talk to them and do a package deal. I saved a ton and the stuff showed up within a week of my order. I will recommend to anyone and everyone.

Trustworthy and dedicated to customer.

Bought items as a kit and not all arrived. Diesel ops reached out to me and made me aware of problems with certain distributors. They were very helpful. And shipped unrecieved parts quickly.

Lack of communication

shipping information was never updated and when we called because it had been over a week since we ordered they had not even shipped the product out. Chris called to explain what went wrong and offered some suggestions to not have this happen in the future.

Charlene,

I want to apologize again about the issue that we had this is something that has been addressed and should not be able to happen again. I realize we did expedite the shipping on this when it did go out but it was still not out in the time that we strive to meet. This is not ever what I like to hear and what I ever want you to have this kind of problem. You will not have this issue and I am glad we were able to come to not only a understanding but a resolution that will work out for you and help you out,

Please let me know if there is anything else I can do to help you out or anything else that you need.

Thank you
