AVAILABILITY: Due to high demand and rigorous quality control standards, current lead time for this machined kit is 1-3 weeks. Orders are processed in the order received.
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.
- De-lipped Fuel Bowl: The piston crowns receive a crucial machining modification where the fuel bowl lip is de-lipped. This corrects the fuel spray trajectory to prevent impingement and remove potential hot spots, thereby significantly reducing the risk of piston cracking under high heat and pressure.
- 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.
- Performance Benefits: This heat reduction provides multiple benefits:
- Lower EGTs (Exhaust Gas Temperatures)
- Lower Oil Temps
- Increased HP & Fuel Mileage
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: Each piston comes with a full set of high-quality standard rings. Designed to meet original specifications, these rings provide dependable sealing and oil consumption control for long-term engine health.
- Wrist Pins and Locks: Includes heavy-duty wrist pins and corresponding locks (or retainers) for secure connection to the connecting rod.
Piston Set Includes:
-
