AltMount's additional alternator mount kits and serpentine pulley systems allow you to have a higher-output alternator to meet your battery charging needs. This allows for multiple configurations, including having one as an emergency back-up, switching between output levels, dedicating each alternator to specific batteries/battery banks, or combining the power of both alternators.
