Balmar Alternator 120 AMP Kit 120V 3.15" Dual Foot Saddle J10 Pulley Regulator & Temp Sensor

The Balmar Alternator 120 AMP Kit 12V with 3.15" Dual Foot Saddle, J10 Pulley, Regulator, and Temperature Sensor is an essential upgrade for marine and automotive applications that require reliable, high-output power generation. This 120-ampere alternator is designed for operators who need sustained electrical output in demanding environments, particularly those running multiple auxiliary systems, winches, heated cabins, or integrated electronics that exceed stock charging capacity.

The dual foot saddle mounting design provides robust mechanical support and vibration isolation, which are critical for engine longevity and alternator reliability in rough operating conditions. This complete kit includes Balmar's sophisticated regulator and integrated temperature sensor, which automatically compensates for ambient conditions and battery state to deliver optimal charging voltage across all operating temperatures. The 3.15" J10 pulley accommodates standard serpentine belt systems.

Professionals installing this alternator will appreciate its lightweight design at 16.1 lbs, making it suitable for vehicles where weight distribution is critical. The dual foot saddle configuration distributes load stress across the engine block more evenly than single-point mounts, reducing mechanical strain and extending service intervals. This alternator is ideal for marine, RV, truck, and off-road vehicle applications that require a dependable 12V power source.
