Proform Black Crinkle Alternators

Thanks to Proform's Ford Modified 10SI and GM CS130 Alternators with the Black Crinkle finish, you can keep the power flowing to your battery in low-rpm situations.

Electric fuel pumps, A/C, power windows, and even car stereos are too much for OEM 63-amp alternators. The increased power demands of today’s hot rods call for a much-needed upgrade!  

Thanks to Proform’s Ford Modified 10SI and GM CS130 Alternators with the Black Crinkle finish, you can keep the power flowing to your battery in low-rpm situations. Both alternators feature an external fan, 1-wire hook-up, machined pulley, and internal regulator. As with all Proform 12-volt engine parts, these alternators are produced and assembled by highly experienced personnel. Using completely 100% new components, not re-man or refurbished.
