• Windings are made from an elite material with greater strength and efficient current carrying capabilities than standard wiring.

• Regulator features surface mount technology for improved monitoring and high voltage protection.

• Unique rectifier assembly is designed for optimum control even through excessive heat cycles.

• Dual NTN bearing arrangement is capable of enduring loads over 20,000 rpm.


Choosing the correct alternator:
Choosing the right APS Alternator for your engine is easy! First, select an Alternator that will produce the right amount of current to meet the demands of all your vehicle’s electronics. Next, pick the appropriate Bracket Kit for your engine combination, then select a Pulley.

Step 1 - Select an APS Alternator:
Two versions of the APS Alternator are available with three different output ratings. The direct Plug-In models are made to accept many
different factory connectors while the One Wire design uses a single wire connection to the battery for a simple and clean installation. Each connection type is available in 105 amp, 130 amp and 160 amp applications.

Step 2 - Select a Bracket Kit:
Each Bracket Kit is supplied with the necessary mounts to install your APS Alternator to your engine. The brackets are CNC machined to form a precise fit and strong foundation. If you are choosing a Plug-In APS model, be sure to get the Bracket Kit with the matching wiring harness for a direct plug-in connection.

Step 3 - Select a Pulley Kit: Each Pulley is cut from a billet of aluminum and is supplied with a great looking MSD cap to cover the mounting nut. The Pulleys are designed to give you an approximate 3:1 ratio with a standard crankshaft pulley.
