Crankshaft End Seals

A crankshaft end seal forms an air tight seal between the crankshaft and the crankcase. Because an air leak in your crankcase can cause damage to an engine, it is imperative that your crankshaft end seals are working properly and are not causing any leaks. SBT's crankshaft end seals are durable and able to withstand excessive heat, oil, and pressure to enhance your engine's performance. Depending on the manufacturer, each engine contains different types of crankshaft end seals. If only one or two of your seals are worn, SBT offers individual crankshaft end seals for sale for your PWC engines.
