I've been going to the DMax store in Diamond Springs since I purchased my 2006 GMC Sierra 2500HD. I've had nothing but Excellent service and parts purchases. Everyone in that store/service center are professional friendly employees.

Ryan and his team were very knowledgeable. Answered all the questions I had. Got my truck in and out of there in a day for a lift pump install. Gave me multiple options of mounting location. We’re very communicative. Going back for a kryptonite front end soon. Awesome team!

Wish I had discovered this shop earlier. They know Duramax trucks inside and out. Courteous and professional. Busy place... for good reason.
