Great customer service I placed the order over the weekend, we realized the truck we needed the parts for was going to need a lot more work and just wouldn't be worth doing. I emailed the company and asked for the order to be cancelled. I received a reply first thing Monday that the order was cancelled and a refund had been issued. Great customer service.

Lifelong Customer Shipping and Customer Service keeps me coming back. DHD always have what i need and when I need it. Had an Issue (honest mistake) with an order awhile back. There was no issues and it was resolved quickly and painless.

The best diesel performance site Great prices. Fast shipping with reasonable shipping costs. Expert technical support on their products. Out of all the diesel performance vendors I keep coming back to DHD.

Customer support was great Customer support was great! I wanted a federal lb7 down pipe, but they didn’t show any so I ordered a California emissions down pipe and was gonna make it work. It shipped out fast, and on the bottom of my order was a hand written “ i found ya a federal one”… made my day! Thank you again!

So far I’m enjoying dhd’s customer… So far I’m enjoying dhd’s customer service, I deal with a lot of Duramax’s at my shop and they are the perfect vendor for me. Their website has the most available duramax parts I’ve seen throughout my vendors.
