About Merchant Automotive
Merchant Automotive, LLC was founded in 2004 by Eric Merchant. Eric was a long time employee of GM dealerships before forming Merchant Automotive, LLC. Eric got his start in high school where he discovered his passion for anything with a motor. He took his passion and turned it into a career in 1993 working in a small shop doing brakes and alignment work. He accumulated knowledge daily and soon took a position at a GM dealership in 1995 and advanced up the ranks over the next 10 years. Along the way, Eric studied the business hard, taking over 3000 hours of GM training and maintaining ASE Master Certification since 1998.
In April 2008, Merchant Automotive moved into its current location in Zeeland, MI. The move was a huge undertaking that involved a complete remodel of the building. That building, having over 10,000 sq ft of space, has allowed for greater expansion and a large retail front.
Merchant Automotive staffs only professionals who have an intimate knowledge in all the Duramax/Allison platforms and are dedicated to 100% customer satisfaction. Merchant provides you with highly specific technical information not found anywhere else, and many of their products are custom designed and manufactured in-house to maximize the performance and reliability of your truck. The emphasis on product design and specialized manufacturing means that MA can offer you low pricing on products not found at other companies.

Water pump fixed
"Noticed my LBZ overheating and constantly cycling open and closed thermostats, replaced both thermostats and water pump and it’s like a new truck. Runs at operating temperature and regulates as necessary"
Good parts
"Have yet to put in the water pump since I’m waiting for the time to do it, but everything arrived as advertised."
Great product
"Water pump was everything I expected!"
MA Water Pump Failed Within An Hour
"The water pump failed in less than an hour. The teeth were sheared off of the pump gear. 100% part failure and ABSOLUTELY NOT IMPRESSED with Merchant Automotives response or handling of the warranty. Still have not received my refund for the pump and MA is balking on covering any of the tear down to remove all gear teeth from the front cover and oil pan ($1327). Also damaged 3 of the injector pump gear teeth. I'll never buy another MA part and will tell all of my experience."
