The S&S Cycle Piston Kit part number 106-5513 is designed specifically for 80-inch stock big twin motors, providing reliable performance for your motorcycle rebuild or upgrade. These forged pistons offer superior strength and durability, ensuring long-lasting operation under demanding conditions. The kit includes a set of pistons, rings, wristpins, and clips, making it a comprehensive solution for your engine overhaul. Crafted in the USA, these pistons feature a wrist pin deck height of 1.270 inches, optimized for compatibility with standard-length connecting rods.
To achieve optimal performance, it is essential to use connecting rods with a length of 7.440 inches (OEM #24281-74A). Using earlier connecting rods with a length of 7.470 inches (OEM #24281-41A) can lead to a slight increase in compression ratio of about half a point and may cause clearance issues. Carefully check all piston-to-cylinder head clearances when installing early-style rods to prevent potential engine problems. This piston kit is compatible with stock components and is ideal for riders seeking a reliable, low-compression piston solution for their 80-inch big twin engine.
Engineered for precision and built in the USA, the S&S Cycle piston kit ensures quality and performance. Whether rebuilding or upgrading your motorcycle, this kit offers the strength, compatibility, and peace of mind needed for a smooth and efficient ride. Trust S&S Cycle to deliver high-quality parts designed to meet the demands of serious riders and mechanics.
