Trailer Units

X4 Series (7300 & 7500)

A proven platform, advanced performance, low noise and low cost operation are just some of the many features that make Carrier trailer units the world standard. Our innovative technology provides reliable and sustainable products that are designed to meet the needs of every customer application.

The X4 platform features a smarter large-displacement 2.2-liter engine equipped with enhanced sensors and an electric control module. The engine continually communicates with the APX Control System to optimize performance and eliminate wasted power. The result: an ultra-high-efficiency platform that generates higher capacity and performance using significantly less power. That means X4 engines operate using fewer run hours at lower speeds, increasing their durability and reliability.
