"Shannon is the man! 10/10 would recommend. Head gaskets went out on my wife's Subaru Outback, and I got a call the NEXT DAY that they were done. Best turnaround time and the best price. Quality work, knowledgeable and friendly — he'll be my first call if I ever need work done again."
— Marshall M.
"Working with Shannon was the best experience I've had with any machine shop. I brought my heads in for valve seats and valves to be re-cut along with a warp check and resurface. Turnaround was great and customer service was fantastic. All of my engine machine work in the future will be going to Barons."
— Michael M.
"I supervise a fleet of trucks and was in desperate need of a specialized component that was hard to get. It was made at Barons in a very quick time frame and was perfect. I've recommended this shop to many people since, and stand by the professionalism and quality of work."
— Robert D.
