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 smooth. From 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 an 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.
