Whether you're hitting the drag strip, the circle track, or the street, our compact, 10SI-case Lightning-Bolt™ Mini-Alternator delivers massive power, physics-defying weight savings, and head-turning style. Weighing in at only 7 lbs—nearly 40% lighter than a standard 10SI—and pumping out 80+ amps at idle with over 100 amps at the top end, this 12-volt, 1-wire powerhouse packs serious charging performance. An optional direct-fit 10SI adapter makes upgrading even easier.
