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.

Improved performance

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.

Enhance

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.

Durable

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.
