Build a Better Duramax Truck

Great transmission & parts. Customer service is second to none. Perfect parts for the restoration of my 06 LBZ.

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!

Well, what can I say, pick up my new transfer case, I did the install myself because the shop was not ready to go yet. The the transfer case has been flawless and does what a transfer case does. Thanks guys for all your help. Took me look enough to post something but, better late than not at all. Have a great year.

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.
