+ BRACKETRY

A Promaster dual alternator bracket from APS allows for the installation of new primary and/or secondary alternators for increased charging capability, ample power at idle or both. Our dual alternator brackets:

May be installed with minimal disruption to OEM components
Use existing mounting points
May be installed on a separate drive system to avoid interference with the original, OEM drive. (For example, we can create a split system operating at two different voltages.)
Include complete installation instructions

+ MORE OPTIONS

More power at idle: Our high idle switches allow end-users to access more power at vehicle idle with the flip of a dash-mounted switch. These are often sold as part of a dual alternator kit.
Better batteries: APS recommends high-quality AGM, or lithium-ion battery solutions, when developing configurations.
Additional power components and accessories: APS also provides components including DC to DC boost converters, DC to DC step-down converters and battery isolators, to ensure dependable power to all vehicle equipment and systems.
