Balmar 95 Series AltMount Serpentine Pulley

Description

The Balmar AltMount Serpentine Pulley is a ten-groove J10 pulley designed specifically for Balmar 95 Series alternators. It provides the alternator-side drive component needed when building or servicing a compatible J10 serpentine charging system.

The pulley measures 2.7 inches in diameter with a 0.875-inch bore. Its ten-rib profile provides greater belt contact than a conventional single-V pulley, which can be important when a high-output alternator requires the engine drive to transmit more mechanical power without belt slip.

Because serpentine charging systems depend on correct pulley alignment, groove count, bore size, and belt length, this pulley should be matched with the appropriate engine-side pulley system and mounting hardware rather than used as a generic replacement. It is particularly relevant to installations using Balmar AltMount conversion components or maintaining an existing 95 Series J10 setup.

For owners servicing or configuring a 95 Series alternator with a ten-rib serpentine drive, this Balmar pulley provides the correct J10 profile and documented dimensions for the alternator. We carry more in our alternator mounts & pulleys.
