Review SUZUKI New Genuine Piston Ring Set 1.00 O/s Oem

Introducing the Suzuki 12140-40B30-100 piston ring set, an essential upgrade for your Suzuki outboard engine's cylinder assembly. This piston ring set is specifically designed for 1.00 over-sized (OS) bore sizes.

Each ring in this set is meticulously crafted using high-quality materials to ensure superior performance, reliability, and durability. The rings are designed to provide an optimal seal between the piston and cylinder wall, reducing the potential for combustion gas leakage and improving overall engine efficiency.

The Suzuki 12140-40B30-100 piston ring set includes four rings: an upper compression ring, a lower compression ring, an oil control ring, and a bottom oil scraper ring. Each ring is precision-engineered to fit snugly in place and work together to optimize engine performance.

The upper compression ring is responsible for sealing the combustion gases within the cylinder during the power stroke. It is designed to provide a strong compression seal while also allowing for easy piston movement during the intake and exhaust strokes.

The lower compression ring, also known as the second compression ring, helps to further improve the combustion seal and reduce blowby. It is designed to work in conjunction with the upper compression ring to optimize engine efficiency and power output.

The oil control ring, located between the upper and lower compression rings, is responsible for preventing oil from escaping into the crankcase during the combustion process. This ring helps to maintain proper oil pressure and ensure consistent engine lubrication.

The bottom oil scraper ring is located at the bottom of the piston and is responsible for scraping excess oil from the cylinder wall and returning it to the crankcase for reuse. This ring helps to ensure that the engine receives a consistent supply of oil while minimizing oil consumption.

Overall, the Suzuki 12140-40B30-100 piston ring set is an essential upgrade for any Suzuki outboard engine in need of a cylinder assembly overhaul. With its high-quality materials, precise engineering, and reliable performance, this ring set is sure to provide a significant improvement in engine efficiency, power output, and overall longevity.
