When high-performance engine modifications are made, the increased torque is transferred via the crankshaft to the drive system, putting a significantly higher load on the bearing.
- The Lefty Bearing is case-hardened on the inner and outer race to provide increased load capacity and enhanced durability in high-torque applications
- The bearing is installed in the left side of the crankcase, and supports the output shaft to the primary drive system
