DynoCams offers Compression Rings, Scraper Rings, and full Ring Sets for Clone, Animal, and Flathead Go-Kart Racing Engines. DynoCams started with ring development in 1995 with the Briggs & Stratton 5HP Flathead Engine. Through the need for High Quality Piston Rings we developed the DynoCams Compression and Scraper Ring for the Flathead and then added the Animal rings. Recently we added the Low-Tension rings for the Ducar 6.5HP engine with great success. We offer varying sizes and rings depending on the type of Engine you have.
