About This Product
MCS outer plate for the primary chain tensioner. This is the OEM-style replacement for 39993-65 on 1965 to 2000 Big Twin models. It does not fit 2006 Dyna models. The plate gives the tensioner assembly a flat, durable surface to work against. Once it grooves or warps, the primary chain runs rough and wears fast. Swap it during a primary service and the chain and sprockets last longer. Quietens things down too.
Manufacturer part number: 999365.
