The S&S CYCLE Piston Kit (Part #106-5512) is designed specifically for 80-inch stock big twin motors, offering enhanced durability and performance for your motorcycle engine. These forged pistons provide superior strength, ensuring reliable operation under demanding riding conditions and long-term use. The kit includes a complete set of pistons, rings, wristpins, and clips, making it a comprehensive solution for engine rebuilds or upgrades.
Constructed in the U.S.A., these pistons feature a wrist pin deck height of 1.270 inches, optimized for compatibility with standard-length OEM connecting rods (Part #24281-74A) measuring 7.440 inches. When used with earlier connecting rods (Part #24281-41A) measuring 7.470 inches, the piston assembly may experience a slight increase in compression ratio by approximately half a point and potential clearance issues. It is recommended to carefully verify piston-to-cylinder head clearance when using early style rods to prevent engine problems.
This low compression piston kit is ideal for riders seeking increased reliability and performance in their stock motor applications. The forged construction ensures longevity and resistance to wear, while the precise manufacturing maintains proper fitment and engine balance. Whether you're performing a rebuild or enhancing your engine's efficiency, this piston kit provides a high-quality upgrade that meets OEM standards and exceeds expectations for durability and performance.
