GZP Polish rr brake cylinder 3/4" K-Haye

These billet aluminum custom rear master cylinders feature one blind hole and one thru bore hole for clean mounting on the Softail type forward controls. The 3/4" bore is stock replacement for our billet forward controls like ZPN056150 but does not feature the ball milled grooves. The 5/8" bore version is stock on our forward controls ZPN 055101 & 055102. They can also be used, without any modification, on many other FL, FX and FXST forward controls as well as other custom applications.
