  • 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
  • Installed in the left side of the crank case, and supports the output shaft to the primary drive system
  • Fits 2003 and later Twin Cam, and 2017 and later Milwaukee-Eight engines.
