Anti-Rotation Lifter Pins / '99-'17 Twin Cam

Fresh anti-rotation pins, in stock size and a 0.002 inch oversize for worn bores. The anti-rotation pin keeps the lifter square in its bore. As the bore wears the clearance opens up, and a Harley-Davidson Twin Cam gets noisier for it. New pins bring that clearance back, and Feuling states the result is a balanced and quieter engine. Two sizes are offered. Stock replacement suits a bore still in good shape. The 0.002 inch oversize is there for a bore that has worn past what a standard pin can take up. Feuling recommends a maximum clearance of 0.002 inch to 0.003 inch between lifter and anti-rotation pin New pins create a balanced and quieter engine with proper pin clearance Available in stock replacement and 0.002 inch oversize diameter Made in the U.S.A.
