5.9L Cummins Choate Pistons w/rings 20 over 04.5-07 Coated, Flycut Set.

Key Features and Fixes:
Choate Engineering Performance incorporates critical features to solve common performance constraints and provide a robust foundation for high-horsepower builds.

• Polyphen Coating Tops: The Polyphen Coated Tops act as a thermal barrier to reduce heat transfer into the piston material and oil.
• Performance Benefits: This heat reduction provides multiple benefits:
  • Lower EGTs (Exhaust Gas Temperatures)
  • Lower Oil Temps
  • Increased HP and Fuel Mileage
• Versatile Use: These pistons are suited for every day use and racing, making them ideal for the daily driver who occasionally tows or the dedicated track competitor.
• Valve Clearance Solution: The flycut valve reliefs eliminate the common constraint of piston-to-valve interference encountered when using performance cams, allowing builders to confidently select higher lift camshafts.

Components and Parts:

This complete kit provides a ready-to-install solution built for durability under high-stress conditions.

• High-Strength Piston Castings: Built from robust materials capable of withstanding the elevated cylinder pressures and high temperatures common with aggressive tuning and high boost levels.
• Complete Ring Set: A full set of performance piston rings is included for each piston. These rings are designed for optimal cylinder sealing, maximizing compression, and controlling oil consumption.
• Wrist Pins and Locks: Includes heavy-duty wrist pins and corresponding locks (or retainers) for secure connection to the connecting rod.

Piston Set Includes:

• 6 Pistons with Ceramic Coated Tops
• Non-coated Piston Skirts
• 6 Pins
• 12 Locks
