Wilwood 260-10280 Compact Remote Die Cast Master Cylinder Body Assembly 1-1/8 in. Bore

The Wilwood 260-10280 is a Compact Remote Die Cast Master Cylinder Body Assembly featuring a 1-1/8" (1.125") bore, engineered for high-performance street, racing, and custom applications where space is at a premium. Machined from a high-pressure die casting of premium-grade aluminum alloy, this body assembly delivers the output capacity of a full-size master cylinder in a significantly smaller package.

Key Features:

• Ultra-compact 3.37" body length provides 2.16" of additional clearance between the mounting flange and the fluid outlet — ideal for tight engine bays and restricted mounting areas
• 1-1/8" bore optimized for power brake applications, including vacuum-assist and hydraulic-assist systems
• Full 1.12" piston stroke meets or exceeds the stroke capacity of most full-size master cylinders
• 1/8" NPT fluid outlet port located at the top radius of the cylinder bore, minimizing the risk of trapped air during bleeding
• Black E-Coat aluminum body resists corrosion and provides a durable, long-lasting finish
• Compatible with direct-mount or remote fluid reservoirs for flexible installation configurations
• Fluid inlet port accepts 11/16"-20 internal threads for custom reservoir arrangements
