Description
A reliable alternator is the foundation of any high-performance electrical system—without adequate charging capacity, you’ll compromise ignition stability, fuel injection precision, and auxiliary system performance. This GM CS130 140-amp unit delivers consistent voltage output across the RPM range, making it essential for both naturally aspirated and forced-induction builds that demand reliable power delivery. The robust aluminum construction and black powder coat finish ensure durability in engine bay environments while the 6-rib serpentine pulley integrates seamlessly into existing belt systems.
