Eric and his team have worked on my DuraMax going all the way back to 2005. They are top of the line! They have also just moved to 286 Hedcor Street on the south end of Holland.

The team at Merchant is extremely helpful. I was able to get everything I needed to do my head gaskets from them and the heads I ordered arrived quickly. Would definitely recommend them for any Duramax needs.
