Diamond pistons are engineered with only one thing in mind: Winning races! They are manufactured in the USA from 2618 material. Diamond racing company is known from the late 60s to produce the highest quality engine parts around. The past 2 decades Diamond has solely dedicated itself to manufacturing forged pistons. With all state of the art machinery they offer customers the state of the industry in machining. The Coordinate Measuring Machine (CMM) is one of several sophisticated pieces of measuring and modeling apparatus used in Diamond’s engineering department. The CMM provides very accurate measurements, measuring the location and details of valve pockets, for example, to within a .0001in. This laser scanner is used for modeling purposes, especially for scanning piston domes where it scans thousands of surface points in minutes. Developing the highest quality pistons in the industry by using the latest CNC machinery and computer software aids, as well as providing unmatched quality control. With these credentials it was only a matter of time before we decide that this is the firm to work with for making unlimited horsepower!
