APS adds dual alternator kit for Toyota LC300 3.3L diesel

June 03, 2025

American Power Systems, Inc. has unveiled its latest product for the Toyota Land Cruiser 300 – a dual alternator bracket kit designed to add more power to the popular LC300 with a 3.3L diesel engine.  APS now offers dual alternator brackets for 2022 and newer 3.3L diesel and 3.5L gas versions, alongside high output alternators and high-idle kits, giving APS customers a full suite of power solutions for their Land Cruiser 300.

The dual alternator bracket kit lets users add more power to the vehicle with APS’ 12-, 24-, or 48-volt high output alternators, resulting in 12-12, 12-24, or 12-48 secondary system configurations. What’s more, the addition of a second alternator can be done with minimal changes to the OE under-the-hood configuration.

In addition to the dual alternator bracket kits, APS offers multiple high output alternators designed specifically for the Land Cruiser 300, including their latest 290-amp and 390-amp Ultra Performance at Idle (UPI) alternators, their 255- and 360-amp HPI alternators as well as high-idle kits for both the 3.3L diesel and 3.5L gas engines.

"Providing a full suite of power products for the Land Cruiser 300 ensures our customers can rely on robust and versatile solutions tailored to their needs, whether they're navigating remote terrains or supporting additional weight in dangerous environments,” said APS President & CEO Amy Lank. “At American Power Systems, we provide our clients with innovation and dependability every step of the way to help them get the job done no matter where the mission takes them.”

Enhanced electrical power for safety and connectivity in the field

APS has a long-standing history of developing durable, high-output OE replacement alternators for various Toyota platforms, including previous Land Cruiser series, Hilux, Fortuner, Tacoma, Tundra, Hi Ace, and Regius, among others. These Toyota platforms, often used as security or defense vehicles, are frequently equipped with armor and specialized equipment such as anti-IED jammers, communication systems, satellite equipment, and cooling systems.

This equipment enables end-users to stay connected, gather information, and perform silent watch activities. However, the added weight and current draw from this equipment exceed the capabilities of OEM systems. By utilizing a dual alternator setup, end-users have the power needed to not only perform their duties but stay safe and protected in the field.

Tested to withstand the harshest environments to deliver stable, dependable power

To ensure APS products meet its threshold for superior quality and performance, all new products -- including those for the Toyota Land Cruiser 300 -- undergo a rigorous engineering process and testing to industry standards for 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. 

"There is a reason why APS is globally trusted," Lank said. "We have a worldwide reputation for quality, innovation, and expertise. When our products hit the market, we feel confident in their performance because of how meticulous we are behind the scenes during their development."
