Purpose-built for high-performance street, racing, and specialty vehicle applications where space is at a premium, this body delivers full-size master cylinder output in an ultra-compact package.

Key Features:

• Ultra-compact 3.37" body length — provides 2.16" of additional clearance between the mounting flange and the fluid outlet, making it ideal for tight engine bays and custom brake pedal assemblies
• 7/8" (0.88") bore diameter — delivers precise, consistent brake fluid displacement suitable for club sport, open-wheel, and custom performance builds
• Full 1.12" piston stroke — meets or exceeds the stroke capacity of most full-size master cylinders, accommodating short pedal ratios and large-piston calipers
• 1/8" NPT fluid outlet port — positioned at the top radius of the cylinder bore to minimize trapped air and simplify bleeding
• Black E-Coat anodized aluminum body — corrosion-resistant finish provides long-lasting durability in demanding environments
• Compatible with remote reservoir mounting — enhanced fluid inlet port accepts standard Wilwood reservoirs (reservoir kits available separately under P/N 260-7577 or 260-8742)
• Replacement body assembly for Wilwood Compact Remote Master Cylinder Kit P/N 261-16839-.88 and 260-10374
