Compact and lightweight. APS high output alternators pack more power into a smaller, lighter case. Clients often are surprised to learn how much power we can fit into the stock alternator position. APS alternators can double or triple a vehicle’s OEM output. With a dual alternator solution, we can provide as much as five times more power.

High efficiency. Most APS alternators are rated as highly efficient, which denotes efficiency of 80 percent or greater. High efficiency units require less energy from the vehicle’s engine and therefore consume less fuel. Therefore, these units cost less to operate and contribute to less engine wear than other options.

Self-cooling. APS high output alternators self-cool with singular or dual internal fans and high-performance heat sinks, allowing the user to work these units hard without overheating or causing damage to other equipment.

Tested, proven durability. With over 2,000 vehicles currently in the field and 18,000 test miles logged at the Nevada Automotive Test Center, our high output alternators withstand the harshest environments to deliver stable, dependable power.
