Product Advantage
Experience unparalleled charging speed with a peak output of 130 amps. This high output ensures your vehicle's battery is rapidly recharged, significantly reducing the risk of drain even when powering multiple electrical accessories. The advanced internal rectifier and robust voltage regulator maintain a stable current, protecting your vehicle's entire electrical system from surges or under-voltage. This translates to reliable starts and consistent performance, making it an ideal upgrade for demanding electrical loads.
Built to last, this alternator utilizes Class-H high-temperature enameled copper windings and precision-balanced rotors. These premium materials resist degradation from extreme heat and continuous operation, far exceeding the lifespan of standard components. The housing is constructed to resist corrosion, and the internal bearings are rated for over 100,000 hours of operational life. This rigorous construction ensures reliable performance in harsh environments, providing peace of mind and a superior return on your investment.
Efficiency is at the core of this alternator's design. It operates at an exceptional 85%+ efficiency rate, meaning more engine power is converted into usable electricity and less is wasted as heat. This reduces the load on your engine, contributing to better fuel economy. Integrated with an advanced cooling system and high-grade diodes, it maintains optimal operating temperatures even under continuous high-load conditions, preventing performance drop-off and ensuring long-term reliability.
Every unit undergoes stringent bench testing to meet or exceed original equipment (OE) specifications for output, noise, and vibration. This commitment to quality guarantees a perfect direct fit, requiring no modifications for a seamless installation. Backed by a 24-month warranty and supported by a 98.5% factory pass rate, this alternator delivers the peace of mind that comes with a product built to the highest standards of quality and reliability.
Beyond raw power, this alternator is engineered for refinement. The rotor is dynamically balanced to minimize vibration, while the high-quality brushless design ensures exceptionally quiet operation. The use of ISO-certified bearings eliminates whining and grinding noises, providing the silent, smooth performance that is a hallmark of a truly premium automotive component. You get powerful charging without the annoying noise.
