Product Details

This pack gives you five O-rings for the inner primary to case seal on a wide range of Harley-Davidson Big Twin and Dyna motorcycles made between 1982 and 2006. These are the seals that keep your primary fluid contained and prevent dirt from getting in. When you're rebuilding the primary or just need to reseal it, having a fresh O-ring is crucial for a leak-free assembly.

These O-rings are made in the USA and are designed to replace the Harley-Davidson part number 11147. They fit many popular models like the Road King, Electra Glide, Heritage Softail, and Fat Boy from those years. Making sure this seal is in good condition is a key step to a solid primary drive system.
