This is a bare 75-series Tilton master cylinder. Ideal as a replacement or if you already have one of my clutch master kits or if are making your own adapter/kit setup.

Tilton 75-Series universal master cylinder kits feature an aluminum cylinder, black anodized for wear and corrosion resistance. Their universal mounting design offers flange, side, or both mounting options, and their caps are screw-in types with seals and baffles.

For these clutches, I recommend the following sizes:

3/4 bore: 
Comp Stage2, 3 and 4
Mcleod Single discs
OS Giken TR2CD, R3C or R4C
RPS Carbon clutches
Tilton Carbon clutches

13/16 bore:
McLeod Twin discs (RST, RXT, RXT1200)
Tilton ST246 (both standard and HD version)
