The S&S Cycle Piston Kit for 80" stock big twin motors is designed for reliable performance and durability. Featuring forged pistons, this kit provides superior strength and resistance to wear, making it suitable for both daily riding and performance applications. The kit includes a complete set of pistons, rings, wristpins, and clips, ensuring a straightforward installation process and compatibility with your existing engine components.
Constructed in the USA, these pistons are optimized for use with connecting rods that have a standard length of 7.440 inches (OEM #24281-74A). When using earlier connecting rods with a length of 7.470 inches (OEM #24281-41A), expect a slight increase in compression ratio of approximately half a point, which may improve power output but also requires careful clearance checks to prevent interference. The wrist pin deck height measures 1.270 inches, and the pistons are designed specifically for low compression setups, ideal for reliable performance in stock applications.
Designed by S&S Cycle, this piston kit ensures quality and precision engineering, providing a dependable upgrade or replacement part for your big twin motorcycle engine. Proper installation and compatibility checks are recommended to ensure optimal performance and engine longevity. Whether rebuilding or upgrading, this piston kit offers the durability and performance expected from a reputable manufacturer.
