Review CP CARRILLO Piston Kit Conversion fits SPORTSTER 883 1200

The CP-Carrillo M5037 piston kit is a high-performance upgrade for Harley-Davidson Sportster 883 and 1200 models. This piston kit is specifically designed for conversion applications, allowing riders to enhance the power and durability of their Sportster engine.

Each piston in this kit is meticulously crafted from forged 2618-T6 aluminum alloy. Forged pistons offer superior strength and consistency compared to cast pistons, ensuring optimal engine performance and longevity. The piston crowns are designed with a dish shape and a compression height of 3.70 inches, providing excellent power output and efficiency.

The piston skirts are engineered with a full-length, 0.030-inch second ring groove, allowing the use of a second oil ring for improved oil control and reduced piston slap. The piston pin bores feature a generous 0.062-inch oversize to accommodate high-performance piston pins and rings.

The piston tops are designed with a unique, CP-Carrillo patented design called the "Quenched Skirt." This innovative feature helps to prevent piston skirt failure by reducing the temperature of the piston skirt during the combustion process. The Quenched Skirt also helps to reduce piston-to-wall friction, resulting in increased power and fuel efficiency.

The piston rings included in this kit are made from high-quality, chrome molybdenum alloy material. The first ring is a compression ring, while the second ring is an oil control ring. The rings are designed to provide optimal sealing and durability, ensuring efficient combustion and oil control.

The piston kit also includes CP-Carrillo's exclusive, high-performance, flat-top piston pins. These pins are made from 303 stainless steel and are precision machined to ensure a perfect fit and maximum strength. The pins also feature a unique, tapered design that helps to reduce friction and improve engine performance.

Overall, the CP-Carrillo M5037 piston kit is a top-quality, high-performance upgrade for Harley-Davidson Sportster 883 and 1200 models. Its forged pistons, innovative Quenched Skirt design, high-quality piston rings, and high-performance piston pins all combine to provide superior power, efficiency, and durability. Whether you're looking to maximize the performance of your Sportster or prepare it for high-mileage use, this piston kit is an excellent investment.
