25+ Years Experience

We have been serving the Baton Rouge metro area for over 25 years in the heavy duty diesel industry.  We have great reviews from our customers and we strive to ensure that build a relationship with each and every one of them.  

Coy's Diesel Was Founded In 2009

In the summer of 2009 Coy Redmond decided to go out on his own. That decision led to an almost immediate need to upgrade and he set out to find a shop that could suit the needs to perform repairs and performance. After searching for sometime we discovered a shop in Gonzales off of Hwy 621 and 44. They called this location home for three years, but had many struggles between keeping good hands and over coming growing pains. In November of 2014 they moved into a new state of art facility off airline highway in Gonzales. Now they have the capability to provide service on all light and medium trucks with the knowledge of certified technicians that have the experience to fix some of the hardest concerns. Coy's Diesel has a great team and they are very blessed and happy to serve south Louisiana and surrounding areas.
