The Chase Bays Clutch Master Cylinder Adapter is the cleanest, most complete solution for upgrading/ replacing your OEM Clutch Master Cylinder. We offer this product for multiple chassis including Nissan S & R chassis, FC/FD RX7, Nissan 350Z, ZN8/ZN6 and many more.
It’s made from 1/8” (3.17mm) thick powdercoated steel, with pressed and welded M8x1.25 studs for a rock-solid, OEM-style install. No guesswork. No drilling. Just a precise fit that works.
Choose from three options based on your build needs:
Adapter Only – Just the firewall plate. Great if you already have a master, fittings, clevis, and reservoir.
Adapter + Tilton Master Cylinder Kit – Adds a Tilton 76-Series CMC in your choice of 0.625” or 0.75” bore, plus all AN fittings and clevis to adapt to your factory pedal.
Full Add-On: Reservoir, Bracket & Hose – Adds our standalone Chase Bays Clutch Fluid Reservoir, mounting bracket, and EPDM feed hose for external mounting. Isolating the clutch fluid system from the brakes is critical for track use, you don’t want heat or failure shared between circuits.
This kit does NOT work with the OEM clutch line, but it does work with the Chase Bays Clutch Line. When you choose the Tilton option, we include the correct 3/8-24 banjo bolt, so you just swap that in place of your M10x1.0 and you’re good to go.
If you’re looking for better pedal feel, a cleaner engine bay and a setup built for track abuse, look no further!
