Extreme Duty Left Side Main Bearing Kit is for all 2003-17 
Twin Cam models. Includes bearing, spacer, thrust washers 
and snap ring. 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 extreme duty 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 2003-17 FLST, FXST, FXD, FLT.
