What Is In This Collection

Gaskets, seals and O-rings for the M8 Softail - top end and rocker box gaskets, primary and derby gaskets, exhaust gaskets, cam chest and transmission seals and bearings, and the complete kits that cover a whole job.

M8 Softail Fitment

M8 Softail covers '18-'26 - Street Bob, Fat Bob, Low Rider S and ST, Fat Boy, Heritage, Breakout, Sport Glide and Softail Slim. Every M8 is throttle-by-wire, so cable-throttle grips and controls do not apply.

Years that change what fits:

  • 2018 - the M8 Softail replaced both the Twin Cam Softail and the Dyna on an all-new frame.

Worth knowing: FXDR and FXDRS are M8 Softails despite the FXD letters, FLXRST is the Low Rider ST and FLXRS the Low Rider S, and FLHC and FLSB are Softails rather than Touring bikes.

Buy The Gasket With The Job

Nothing is more frustrating than having the cover off and the bike apart, waiting on a five dollar part. Gasket kits are specified per motor family and often per year within it, and the material matters - a composite and an MLS head gasket are not interchangeable. Exhaust gaskets are a consumable: they crush to seal and should be replaced any time the pipes come off, which is also the usual cure for an exhaust leak that appeared after a service.
