Jims Forceflow Cylinder Head Cooler will keep your Twin 
Cam® running cooler in stop and go traffic. Jims has come up 
with a a serious way to drop your temperature by as much as 
100 degrees. Although this mounts in the horn location, Jims 
has relocated a horn inside the fan housing. The fan can be 
installed to be turned off manually or it can be regulated by a 
thermostat controlled sensor that monitors head temperature 
and activates the fan when engine temperature rises. This kit 
is highly recommended for performance motors to help extend 
engine life. Complete kit includes high powered fan, housing, 
horn, hardware and all wiring. Kit installs from horn location and 
supported by center case bolt location. Use on 1999-16 Twin 
Cam Touring models.

Extreme Duty Left Side Main Bearing Kit is for all 2003-up 
Twin Cam and M-8 models. Includes bearing, spacer, thrust 
washers and snap ring. When high-performance engine modi-
fications 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 hard-
ened 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.
