27 Tooth sprocket with chain for FLT-FLH & FXR
New PN 159-56S-A
Old PN 159-56S
I thought I had done enough research and had actually talked to a tech online about the sprocket and chain for my road king. Had my local dealer install it and it just was making too much noise. Took it back to the dealer and they called and said it needed a thick shoe for the chain adjustment to be right. I wish the tech or website would have mentioned this.
