This is a 1.25" bore master cylinder that is original spec for 1976 F350 trucks however this master cylinder mounts on most 1968-79 F150, F250 and F350 power brake boosters. Most oem master cylinders have a 1.0" bore master which is a little too small for a larger vehicle. This contributes to a soft or spongy feeling pedal. The larger bore master reduces fluid pressure, but gives much move volume. Please know that if your brake pedal is on the hard side, this will make it harder to push. This pairs very well with most F350 dual diaphragm boosters.

Port size: 9/16 forward port, 3/8 rear port

This is 100% brand new not remanufactured made with high quality materials. OEM part number equivalent is C9TZ2140G.
