Product Description

Harley FLT Evolution Rear Master Cylinder  (OEM #41755-86, 1987-92)

According to Factory references, this particular master cylinder is correct for FLT models, 1987-92.  Essentially, it's the same style unit that was used on other Big Twin models, but the differences between the various units are in the machined locations for the hydraulic connections and/or brake light switches.  Again, this is the FLT version.  For FXR and FXST models, please see our notes below.

Condition is excellent with very little evidence of wear/use.  And we have already disassembled and inspected, and we can confirm a clean bore, clean internals, and very nice seals.  Produced excellent pressure in our bench tests.



FXR: two top ports, one side port
FXST: two top ports, no side port
FLT: one top port, one side port

Please review your own Factory references to verify proper fitment and port configuration requirements.


  • Condition:   Used
