About This Product
If you are working on an early Ironhead Sportster or a vintage K-model, you know that finding quality seals is vital. This Athena gasket is a direct replacement for OEM 37740-57 and is designed for 1952 to 1956 K and KH models, along with 1957 to 1971 XR and Ironhead Sportsters. It provides a precise fit for these classic engines, ensuring that your rebuild or maintenance job stays leak-free. These gaskets are made to handle the unique requirements of vintage Harley-Davidson powerplants, offering the reliability needed for both show bikes and daily riders. When it is time to seal up your transmission or engine cases, trust a component built for these historic machines.
