Before buying my 2010 Peterbilt 387, I did my research. Whatever I bought would have a Cummins ISX and Allison at Haggai would be overhauling the engine. Shop for your mechanic FIRST and then find a truck to match. My truck had 971K on the odometer when I bought it, and it ran fine but I wanted to start off with a fresh engine. Allison did a great job overhauling my CM871 ISX and everyone at Haggai was a pleasure to be around and work with. Allison let me help where I could, cleaning and painting parts mostly but being there nearly every day gave me much insight into the workings of my engine. This is an awesome family run business and you will be glad you brought your business to Haggai!

Finally! I can't say enough good things about Haggai Truck Center and their awesome staff! We purchased a used semi with a Cummins ISX in November and just got it on the road this week! It had issues from the get go and we were down over 4 months chasing running issues. We paid a heck of a lot of money out over that time with multiple shops to have it "fixed". We took the chance and drove it 4 1/2 hours away to Haggai's. They got it in right away, diagnosed it immediately, and repaired it quickly and affordably. And guess what? IT'S FIXED RIGHT!!! I almost can't believe it. It's a drive for us to get to them but we won't be going anywhere else from now on.

Hands down the best repair shop in Georgia. I’ve been using this shop for about 6yrs. I’ve drove over a 1,000 miles just to have these people work on my rig

Would give them ten stars if it was an option. Best experience I've had with a truck shop in years. No corporate Bs here. Jerry is an absolute guru. And he will sit down and explain things. Allison, Katie, Deanna, they all treated me like a friend . Brought in a Volvo with a cm871 that could barely climb a hill empty. Jerry discovered someone else's botched programming and some other half ways fixing that resulted in a truck that barely made it there. It's been over a month now and boost is still the highest I've ever seen the truck make, gets great mileage if I keep my foot out of it, goes up the mountains like I'm pulling a empty trailer, and starts and idles better than it has in the two years we have owned it. Going back as soon as I get a load that way( I'm from MN) to have them check the overhead, install aftermarket boost and egt gauges, and check out my oil leak. Thanks guys, glad rawze recommended your shop. See you all soon.
