Choate Performance 6.6L Duramax LBZ LMM Choate Pistons w rings 40 over 01-05 Coated Flycut Delipped Set CEP7210DKT10MMCFD

Choate Engineering Performance incorporates critical features to solve common performance constraints and provide a robust foundation for high-horsepower builds. Polyphen Coated Tops act as a thermal barrier to reduce heat transfer. The de-lipped fuel bowl corrects fuel spray trajectory, preventing impingement and reducing piston cracking risk. Flycut valve reliefs eliminate piston-to-valve interference with performance cams. These features lead to lower EGTs, lower oil temps, increased HP, and fuel mileage. The complete kit includes 8 high-strength piston castings with ceramic coated tops, non-coated skirts, a full set of high-quality standard rings, wrist pins, and locks. Precision machining ensures optimal geometry, clearance, and quality control.
