Whether we’re talking about your engine, transmission, differential, suspension, or otherwise, correct specifications are necessary to keep your car, truck, or SUV reliable, drivable, and running smoothly. From our team here at Harold's Used Auto Parts Inc in Philadelphia, PA, here’s what you need to know.

Specifications are factory recommended tolerances, clearances, and conditions that must be adhered to as part of regular maintenance. On precision equipment like your vehicle, thousandths of inch specs are the difference between a car that runs and drives smooth for hundreds of thousands of miles and a car that kicks the bucket early and never meets its full potential.

Over time, heat, wear and tear stress, and age can throw tolerances like valve adjustment, front end alignment, transmission shift points, and so on out of recommended limits. In the case of specifications, a simple adjustment is all that’s necessary to restore your car back to like-new operation. Drivability, running condition, and longevity are all dramatically affected by incorrect specifications. Fortunately, our expert technicians are equipped with the knowledge and tools necessary to keep your car finely tuned and road-ready.

No matter your maintenance or repair needs, Harold's Used Auto Parts Inc has your back. For the best auto service shop in Philadelphia, PA, call or stop by today.
