6.7C Choate Pistons w/rings 2019-2024 Coated, Flycut Set

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. Performance Benefits: This heat reduction provides multiple benefits: Lower EGTs (Exhaust Gas Temperatures) Lower Oil Temps Increased HP & 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: 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: 6 Pistons with Ceramic Coated Tops Non-coated Piston Skirts 6 Pins 12 Locks Machining Process: The integrity and performance of these pistons are achieved through specialized machining processes focused on geometry, clearance, and quality control. Precision Flycutting: The piston crowns are flycut with precision-depth valve reliefs. This guarantees the necessary piston-to-valve clearance required when installing high-lift performance camshafts. Piston Geometry: Each piston is machined to specific tolerances and weight-matched to maintain engine balance and ensure consistent performance across all cylinders. Piston Cycling: Each piston goes through vigorous quality cycles at our facility to ensure they meet stringent specifications before assembly and coating. IMPORTANT: There are several piston sizes available. Please be sure that you order the correct size. If you change your piston size after the order has been completed, a restocking and shipping fee may be charged. Standard sized pistons are non-refundable.
