I took my truck in with a bad upper oil pan leak and an injector needing to get fixed, Luke did an excellent job on resealing everything that could possibly give me problems in the future . Resealed all 8 of my injectors while he was at it and upper oil pan resealed etc, Great customer service Luke would give me a call to give me a heads up on parts being delayed due to holidays or any possible problems, my truck has been running great ever since . If I ever run into any problems with my truck again I know I can confidently give Luke a call and he’ll fix up the truck in no time, very happy with the outcome of how everything came out with my truck being resealed and ready to put to work! Great prices and great quality work . I definitely recommend his shop to anyone who is having trouble with there truck
Thank you Luke for the good work and getting my truck back on the road as soon as possible.

Great shop to deal with. Hooked me up on getting my L5p Duramax back up and going again after injector issues. Great customer service, great turnaround time, and professional communication. Will definitely be using them from now on in the future.

Mr.Luke did a great job installing a Fass Fuel system in my dads truck the night before Father’s Day to surprise him. I recommend Southern Built Auto Works to anybody looking for a great shop that does good work for a reasonable price.

This was a great experience. Nothing really but compliments for this shop. I knew it was going to take a little longer because the amount of customers who had come in before me but I was glad Luke was upfront and honest about it. The typical high pressure pump went out and I elected to use upgraded parts which took a like longer than normal but in our society it wasn’t bad. Truck is back up and running good. I feel confident that if I have an issue with my truck I can call Luke anytime and he’s going to help me all he can. Lots of other shops are out there but as long as I own this diesel These guys will be my go too! Thanks Luke and Hunter for all your hard work to get me going again.
