FEULING machined steel, stock replacement roller chain drive sprocket is a direct replacement for the factory outer sprocket, much more precise fit than the loose fitting OEM sprocket on H-D Milwaukee-8 and Twin Cam engines.
FEULING crank sprockets are designed with a tighter tolerance on the ID for better fit to the pinion shaft which aids in eliminating cam timing variance due to poor crank sprocket fit. Testing has shown as much as 4 degree timing variance with the loose fit factory sprockets.
Fits 07-later Twin Cam engines (and 06 Dyna models) & all Milwaukee-8 engines
