Balmar Alternator 170 AMP 12V 3.15" Dual Foot Saddle K6 Pulley

The Balmar Alternator 170 AMP 12V 3.15" Dual Foot Saddle K6 Pulley is a heavy-duty charging solution purpose-built for vehicles demanding reliable electrical output under sustained load. Whether you're upgrading a marine engine, auxiliary power system, or high-draw vehicle electrical architecture, this 170-amp unit delivers the sustained current needed for winches, inverters, compressors, and deep-cycle battery charging. The dual-foot saddle mount and K6 pulley configuration provide flexible integration into existing engine layouts, making it an ideal choice for custom automotive builds and electrical system overhauls.

Built with Balmar's reputation for industrial-grade reliability, the XT-CR-170-K6 employs a compact footprint (3.15" diameter) while maximizing amperage output through advanced internal rectification and voltage regulation. The dual-foot saddle design distributes mounting stress across two contact points, reducing vibration transfer and extending bearing life on long-haul applications. At 14 pounds, this is a substantial charging unit engineered for continuous duty cycles—critical when powering auxiliary equipment that cannot tolerate voltage sag or intermittent charging. The K6 pulley ensures compatibility with serpentine and V-belt drive systems common in automotive and marine powerplants.

Mechanics and fabricators installing this alternator on custom 12V electrical systems will appreciate the 170-amp capacity for simultaneous engine starting and auxiliary load management—eliminating the voltage droop that plagues stock alternators under dual demand. Installation requires basic mechanical knowledge: secure the dual-foot saddle to engine block bosses, align belt tension to OEM spec, and confirm proper pulley-to-pulley spacing. This unit suits trucks, RVs, off-road vehicles, and marine platforms where aftermarket battery banks, chargers, and accessory draws exceed factory electrical capacity. Verify engine mounting points and belt configuration before purchase to ensure dimensional compatibility with your specific application.
