Shop Aftermarket Diesel Parts for your Cummins, Powerstroke, Duramax, or any Diesel Vehicle. We specialize in quality products with better customer service!
Website was easy to order off of but did not have great descriptions of some of the products. I ordered 2 parts. One wasn't right and the description didn't state enough info. The other part I ended up not needing. 2 emails later and about a week's wait and still no response from customer service about sending them back.

Fast delivery! Ordered and it was delivered in two days time.
Fast shipping is amazing. Got all my parts for a steal as as well. Thank you
The business aspect of ordering, paying and receiving my products was A+. I received the right parts and they shipped quickly receiving them only 3 days later. The exhaust system I ordered from Flo-Pro had a bent section i had to manipulate to get it to fit and one of the clamps was missing a bolt. The EGR delete kit started out fairly easy and went flawlessly until one of the exhaust manifold bolts broke off. That was almost 1,000 dollars of unexpected expenses but no fault to Diesel Ops. They do a very good job of getting you the parts you order to you quickly and they recognize military members by offering a discount. As a veteran, thank you. If or when I need to order aftermarket parts again I'll turn to Diesel Ops.
These guys were great! So happy I made the purchase with them!
Items were exactly as described. Shipped quickly and for free. Saved a ton and super happy with the truck. Diesel ops is the only place to get performance diesel parts!
Diesel ops is easy to deal with. Product was just as described. Quick shipment.
Exhaust pipe and tuner was as shown and delivery was on time.The kit woke the truck up as never before! Great product /Great service.
Having problems downloading H&s minimax tuner will not commit with my computer

excellent customer service! I had some question about the install on my truck and had all the answers right away.
The item was shipped and received in the time frame stated. The quality was great, and works well on my truck. I will order more from Diesel Ops.
I don’t like how they advertise 10% military discount and then once your military status is approved, only then did they tell you of the numerous brands to which the discount doesn’t apply, which was most of the brands and including all kits/packages. If I hadn’t already built my cart the previous week, I would’ve gone somewhere else for an actual discount off my purchase, but I just wanted to get it purchased and done. On the positive side, the people I spoke to you over the phone or nice and helpful, and I like how installation guides were given via email (and on website) for every ordered part
Excellent service and bang for the buck sometimes I can't find the same thing I found before but love this place
Quality products at fair prices. My parts arrived quicker than I could have imagined. Will definitely be back for future upgrades.
Install was easy and awesome. Step by step instructions included! No other parts needed at all! It is the best bang for your buck! Top of the line exhaust setup!
Product was delivered in 2 days (before shipping info was sent). Turns out it was damaged during shipment. I talked to a rep, sent some pics, and BOOM a new one was waiting for me when I got home the next day.
I can't say enough about the customer service. I will indefinitely be ordering from DieselOps again.
