Wilwood 260-10372 Compact Master Cylinder Kit 3/4in Bore Aluminum Black

The Wilwood 260-10372 Compact Master Cylinder Kit is designed for applications where installation space is limited but full-size master cylinder output capacity is required. This version features a 3/4-inch bore, compact aluminum body and an included reservoir.

The ultra-short 3.37-inch body provides additional clearance between the mounting flange and fluid outlet, while the 1.12-inch piston stroke meets or exceeds the stroke capacity of many full-size master cylinders. A top-mounted 1/8-inch NPT fluid outlet helps reduce the possibility of trapped air in the hydraulic system.

Vehicle Fitment

Application: Designed for custom and application-dependent brake systems requiring a compact 3/4-inch bore master cylinder.

Fitment Note: No specific year, make or model fitment is specified. Verify bore size, mounting dimensions, hydraulic requirements, reservoir configuration and brake-system compatibility before ordering.
