Balmar Alternator 1-2" Single Foot J10 Serpentine Pulley - 170A - 12V

The Balmar Alternator 1-2" Single Foot J10 Serpentine Pulley – 170A 12V is designed for high-demand electrical systems in trucks, RVs, marine vessels, and specialty vehicles where factory charging capacity is insufficient. This alternator is ideal for users running auxiliary lighting, winches, inverters, or other heavy-duty loads that exceed the capabilities of a stock alternator.

With a continuous output of 170 amps, this unit provides reliable power for extended periods, ensuring stable voltage for dual battery banks, compressors, or communications equipment. The alternator features a single-foot mounting bracket and a serpentine pulley designed for modern belt systems, simplifying installation compared to older multi-groove designs.

Balmar alternators are favored by mechanics and fabricators for overlanding builds, expedition vehicles, and commercial fleet upgrades where sustained electrical independence is crucial. The compact dimensions allow for easy retrofitting into tight engine compartments without extensive rewiring or custom fabrication.
