Build a Better Duramax Truck

I found what turned out to be a hard to find item (glow plug nuts) on Merchant Automotive. I've never ordered from them before, but they had what I needed at a very reasonable price. I received the package in 3 days via USPS First Class. Packaging was better than I get similarly small and lightweight items in from other large retailers. It's nice to find a specialty retailer online that gets you what you want quickly and at a low price. And the website was easy to use. Great experience!

After a recent transfer case drain and refill, I was worried bout the fluid I put in my case. I watched a Merchant Automotive video which is what prompted me to seek a real professional opinion. The folks over at Merchant Automotive responded to my email inquiry with a great response, and some valuable detailed resources. These guys rock! Thanks!

Ordered a bearing I desperately needed and could find local. Ordered it with 2 day expedited shipping. They had it packaged and in fedex possession in just over a hour. Best service I have ever found online. Thanks again you guys are great.

Merchant Auto should be every Duramax owners first stop for replacement and performance parts! the guys are very knowledgeable and great to work with. installed the MA transfer case brace on my manual 2004 Duramax that is pushing over 560hp and over 1000 ft/lbs at the rear wheels on the dyno. I knew from the second i called that Merchant Automotive was the company to trust with all my needs. i have worked on friends Duramaxs as well and they will tell you nothing but good words about their experience with Merchant Auto after i sent them to the website for fuel system parts.
