Our parent company, Mertz Auto Parts Company, started over 50 years ago in Sunbury, PA. In the late 80’s, we purchased a local machine shop for engine machining services. We moved the business to its present location and expanded the services over the years to include driveshaft assembly, U-bolt bending, and hydraulic hose assembly. An engine dyno machine was also added at our present location. With the help of our hard-working and dedicated employees, the business continues to move forward.
