First Gear employs bore honing when required to deliver exact finishes. This procedure is a very trusted process to create parts that perform at the highest level. Honing is an ultra-precise finishing method of machining to create near perfect roundness, straightness and size as well as creating a crosshatch pattern finish for optimal lubrication.
