Wilwood GS Integral Master Cylinder - .625in Bore

This Wilwood GS Integral Master Cylinder features a .625 inch bore, a size often chosen for applications needing a balance between pedal feel and clamping force. The body is made from high-pressure die-cast aluminum, which keeps the weight down while still being strong. It also comes with an e-coat finish to help protect it from corrosion.

Inside, you'll find a refined return spring and piston assembly that's designed to give you good control over brake pressure. This setup also helps ensure the brakes release quickly and completely after you let off the pedal. The integral design means it has a positive seal using an internal bellows cap, which helps keep contaminants out and fluid in.

This master cylinder is rebuildable, meaning you can service it down the road if needed, which is a nice touch for long-term use.
