Accurate diagnostics and dependable repairs to solve issues fast and correctly.
Oil changes, fluid services, tune-ups, and preventative maintenance to keep your truck running strong.
Custom tuning and performance parts to improve power, drivability, and capability.
Drivetrains have known strengths and weaknesses depending on the vehicle and how it’s used. At Barrett Performance & Engineering, we take those factors into account when diagnosing issues or recommending repairs and upgrades. By selecting the right components—often upgraded when it makes sense—we improve reliability, reduce repeat failures, and help protect your investment over the long haul.
Not all brake and suspension setups are created equal, and what works for one truck may not work for another. At Barrett Performance & Engineering, we evaluate vehicle weight, drivetrain, towing demands, and driving conditions to select the right components for safety, control, and long-term durability. Choosing the correct—or upgraded—parts upfront often improves performance, reduces wear, and helps prevent costly issues down the road.
Electrical problems can be some of the most frustrating and time-consuming issues on modern diesel trucks. At Barrett Performance & Engineering, we focus on proper diagnostics to identify the true source of electrical faults before repairs begin. By repairing wiring, sensors, and electrical components the right way, we help prevent recurring issues, reduce downtime, and restore dependable performance.

"I can’t recommend Barrett Performance and Engineering LLC enough. Brad, the owner, went above and beyond with my Duramax. Instead of just giving me a quick fix like so many shops do, he took the time to really dig in—going through both the motor and transmission from top to bottom, front to back. His attention to detail was incredible, and you can tell he’s meticulous about every single step of his work"

"Huge thanks to Brad at Barrett Performance and Engineering LLC. He went through my man diesel with incredible attention to detail and fixed issues that other shops had overlooked. On top of that, he was fair and honest with labor costs, which really shows how much he values his customers. It’s rare to find a mechanic who combines skill, integrity, and passion the way Brad does. Highly recommended!"

"Barrett Performance was recommended to me by a local mechanic shop that does not do diesel. That meant a lot to me and I was not disappointed. Brad worked on my 28 year old Ford F250 and made it new again doing all the work that I'd put off for so many years and even put the Banks Intercooler kit on it as well. He fixed so many things that needed fixing and in a quick amount of time. I'm very happy and believe my truck has a new lease on life. I can't thank him enough."
