Balmar Serpentine Pulley Conversion KitsBalmar Serpentine Pulley Conversion Kits facilitate the use of Balmar High Power Alternators. It provides, Quieter Motoring, Better Power Transfer, Reduced Vibration and Belt Dust.

Single Vee pulleys can only support alternator power loads (PTO) of up to 100A for 12V applications (45A for 24V applications). A serpentine pulley provides greater surface contact between the belt and pulley, and thus can accommodate much higher PTO requirements.

AltMount® Pulley Kits are designed uniquely for each engine, including all the hardware required to complete the installation. The system is installed by placing and fastening a conversion pulley over the existing crank pulley and replacing the water pump pulley. Two serpentine belts are provided with each kit.

AltMount® Pulley Kits install easily and deliver a marked improvement in power transfer while reducing noise and engine vibration.
