Side-mount CNG fuel systems
Our ProRail® side-mount CNG fuel systems are engineered for high performance, safety, durability, and can be installed on both sides of the frame rail.
Our systems have fuel capacity options from 17-60 DGE and enable up to 13% faster fill up compared to other CNG fuel systems. Our Marathon™ regulator delivers improved low-pressure performance and extended range.
Can be combined with ProCab® behind-the-cab fuel systems for additional capacity and range. Automotive-grade exterior paint can match any fleet’s custom color.
The system is one-million-mile simulated durability tested, and the new improved design builds on ProRail's nearly 10 years of real-world experience.
Lightweight and safe
When weight matters, our lightweight Type 4 cylinders enable trucks to haul more freight. Our ProRail CNG fuel system is developed and tested to exceed industry safety requirements for crash and fire testing, including a patented bumper bar for built-in side impact crash protection.
