The WOSSNER K4083D478-2 piston kit is designed for high-performance engines requiring a 4.500-inch stroke and 120 cubic inch displacement. Crafted with advanced anodized surfaces, this piston kit offers superior resistance to extreme heat, ensuring durability under demanding conditions. The anodization process enhances thermal diffusivity by up to 10%, allowing the piston to manage heat more effectively and reducing wear over time. The hardcoat anodize treatment further improves the piston’s ability to handle sliding wear, extending the service life of key components such as the piston rings and ring grooves. This comprehensive kit includes a piston, piston rings, piston pin, and retaining clips, providing all essential parts for a reliable rebuild or upgrade.
The piston's valve pocket specifications are precisely engineered with an intake diameter of 1.780 inches, intake depth of 0.200 inches, and an intake angle of 27 degrees. The exhaust side mirrors these dimensions, with an exhaust diameter of 1.780 inches, exhaust depth of 0.200 inches, and an exhaust angle of 27 degrees, ensuring optimal airflow and combustion efficiency. The design and materials used in this piston kit are tailored for high-performance applications, making it suitable for enthusiasts and professionals seeking improved heat management, durability, and performance in their engines. With a weight of approximately 50.1 ounces, this piston kit is engineered for balance and stability in demanding engine environments.
