Need to upgrade or replace the brake or clutch master cylinder on your small vehicle? This universal master cylinder is built tough. It's made from high-strength metal, so it's solid, impact-proof, and resistant to wear and deformation – it's made to last. It's designed to give you responsive and sensitive control over your clutch or brake lever, which is super important for safe driving on karts, three-wheeled ATVs, and similar small recreational vehicles. All the components are rigorously tested to meet strict quality standards before they leave the factory. The workmanship is precise and professional. It comes as a single unit (just the cylinder itself), ready for you to install. Please double-check that the fitment and thread sizes are compatible with your specific kart or ATV model before purchasing. A reliable, basic component for your DIY repair or performance mod project.
