The stroked crankshaft in the 96" engine changes the dynamic from 2006 and earlier model 88" engines, making correct cam choice crucial to avoid engine damaging detonation with today's fuel quality. Spring work required unless otherwise noted as a bolt-in cam. We recommend new cam bearings and performance tappets with any cam change. *These cams can also be used in 2006 FXD engines Red Shift 657 Cams for 107" and Larger Engines.
