About Powermaster Performance
Since 1981, Powermaster Performance has been engineering high-output charging and cranking solutions from its facility in West Chicago, Illinois. With more than four decades of hands-on manufacturing experience, Powermaster has grown from a niche performance supplier into one of the most respected names in the automotive electrical aftermarket — trusted by professional racers, custom builders, and dedicated enthusiasts the world over.
What sets Powermaster apart is its deep involvement in the entire product development cycle. The company has cultivated long-standing relationships with original equipment manufacturers, giving their engineers direct insight into how factory components are designed — and where they fall short under demanding conditions. That knowledge is channeled into every product Powermaster builds, resulting in parts that are engineered to exceed industry standards rather than simply meet them.
Starters Built for Demanding Applications
The foundation of Powermaster's reputation is its lineup of starter motors. Whether you're building a high-compression race engine that demands serious cranking torque or simply need a reliable, high-quality replacement for a street machine, Powermaster offers starters engineered to deliver. Their starter lineup covers a wide range of GM, Ford, Mopar, and other popular platforms, with options for both stock and high-performance builds.
High-Output Alternators for Street and Strip
Powermaster's alternators are designed for applications where factory charging capacity simply isn't enough. From high-demand street builds loaded with accessories to competition vehicles that need rock-solid electrical output at all RPM ranges, Powermaster alternators are available for GM, Ford, Mopar, Jeep, diesel, and many other applications. Their high-output designs help ensure that batteries stay charged and electrical systems stay stable — even under race conditions.
Complete Charging System Support
Powermaster goes beyond just the core components. Their catalog also includes alternator brackets to ensure proper fitment and alignment, alternator pulleys sized and spec'd for performance applications, and even wiring harness connectors to simplify installation and integration. This comprehensive parts ecosystem means builders can source everything they need for a clean, complete charging system upgrade from a single trusted manufacturer.
