Choate Performance 5.9L Cummins Choate Pistons w rings 20 over 04.5-07 Coated Flycut Set CEP7195DKT5MMCFD

Choate Engineering Performance incorporates critical features to solve common performance constraints and provide a robust foundation for high-horsepower builds. The pistons feature Polyphen Coated Tops acting as a thermal barrier, reducing heat transfer and providing benefits like lower EGTs, lower oil temps, and increased HP & fuel mileage. They are suitable for everyday use and racing, catering to daily drivers who occasionally tow or dedicated track competitors. The flycut valve reliefs address piston-to-valve interference with performance cams. The kit includes high-strength piston castings, a complete ring set, heavy-duty wrist pins, and corresponding locks. Each set contains 6 pistons with ceramic-coated tops, non-coated piston skirts, 6 pins, and 12 locks. The pistons undergo specialized machining, including precision flycutting for piston-to-valve clearance, precise geometry, and weight-matching for engine balance, with rigorous quality control.
