Keep your alternator safe at high engine speeds with our precision-engineered 75mm outer diameter overdriven alternator pulley. By reducing alternator RPMs, this pulley prevents dangerous overspinning that can lead to premature wear, excessive heat, and electrical system strain.
Perfect for performance racing builds that see frequent high-RPM operation, this pulley helps maintain reliability without sacrificing charging efficiency. Machined from high-quality 6061 Aluminium billet and designed for a direct fit, it’s the ideal upgrade to extend alternator life and protect your car.
