This mainshaft quad o-ring is engineered to create a high-pressure seal that prevents primary oil from migrating along the transmission shaft. The specialized four-lobed design provides multiple sealing surfaces to ensure a leak-free interface even under significant heat and vibration. These precision-molded components offer a dependable fit for technicians performing transmission service or primary drive maintenance.
This part fits 1984-2022 Harley-Davidson Big Twin, Milwaukee-Eight, and Sportster models equipped with a five or six-speed transmission.
