Clutch Masters .75in Bore Master Cylinder Upgrade Kit Black Honda Civic Si 2017-2021 | MC08150-BK

Upgrade your clutch hydraulic system with the Clutch Masters Billet Clutch Master Cylinder, engineered to deliver improved pedal feel, reliability, and performance under demanding driving conditions. This upgrade is ideal for vehicles running aftermarket clutch kits where the factory master cylinder may struggle with increased pressure and wear.

Product Overview (SEO Optimized)

The Clutch Masters master cylinder is constructed from 6061 billet aluminum and designed as a complete plug-and-play upgrade, replacing the factory unit with a stronger, more responsive hydraulic system. It is specifically engineered to provide crisper clutch engagement and improved consistency, especially in performance and high-horsepower applications.
