EBC 2012 Harley-Davidson DYNA FLD 103 Switchback (1690cc) CK Series Clutch KitIf you need to replace worn original plates these are exactly the same technology, size and shape and drop right into your clutch basket. Plates must be oil soaked using standard drive case oil for a few hours before install to avoid heat scorching. Always replace tired clutch springs and check for wear on driven (non lined) plates. If clutch has been slipping before replacement a full DRC or DRCF kit may be a better choice.
