Built as a direct replacement for Harley-Davidson Part DF07A73CS16 (37000168), this ceramic bearing upgrade enhances clutch hub performance in Twin Cam applications. High-precision ceramic rolling elements reduce friction and heat buildup, helping the bearing run cooler and deliver longer service life under repeated clutch engagement. By maintaining proper hub alignment and minimizing drag, it supports smoother power transfer and a more consistent clutch feel. Ideal for performance builds and high-mileage riders, this upgrade offers improved durability and reliability over standard steel bearings.
