- Chrome Aluminium O.E. GM Style Master Cylinder
- 1⅛” bore
- Centre to centre measurement of the mounting bolt holes is 3-3/8”
- 9/16” and ½” ports on both sides
- Four port unit meaning you can mount your lines to either side
- Works for:
- Shallow pocket
- Fits most aftermarket boosters including Cal Custom and MBM, as well as all original GM (same 2 and 4 bolt pattern)
- Considerably lighter than O.E. cast iron master cylinder
- Can be mounted to original firewall location when not using a booster
- When mounting any master cylinder under the floor, residual pressure valves are necessary to prevent loss of brake pressure (they are not usually required for firewall mount kits).
