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.

Key Features

• Installed in the left side of the crank case, and supports the output shaft to the primary drive system
• Actual bearing color may vary
