Brian spent several years at a Ford dealership where he worked and trained to become a Ford certified Master Diesel Technician. In 2012 he opened a shop with the goal of offering a premier diesel service utilizing the best possible parts, not limited to what a dealership could offer. His aim is to provide every customer with the best diesel experience possible, ranging from their everyday work trucks to competition vehicles. After 5 years Brian set aside some time to pursue his goal of having the fastest 7.3 in the world. In March of 2018, he did the unheard of, putting a 7.3 into the 4-second zone for 1/8 mile and is continuing to push innovation and performance across the entire platform. Look for mid 4- second passes in the near future with our full size OBS pickup!

 When Brian Gray ended his professional Motocross racing career, he needed to find something to occupy his skills and time. Brian turned to the diesel industry and opened Gray’s Diesel Performance in 2012. The shop primarily works on Ford and Chevy diesel trucks and is home to the world’s fastest 7.3L Powerstroke.
