A-Frame
Saddle Mounted CNG Systems
Features
1
Optional Steps and Deck
Durable aluminum steps and deck provide convenient access while maintaining a lightweight, corrosion-resistant design. Available in multiple configurations to accommodate vehicle and body requirements.
Flexible mounting architecture allows the system to accommodate varying chassis, wheelbase, and body configurations for easier vehicle integration.
2
Adjustable Mounting
3
Plug and Play
Designed for efficient integration with OEM chassis and body installations, helping simplify installation and reduce vehicle upfit time.
4
A-1 InSight
Optional digital fuel monitoring provides operators with real-time system information and enhanced fuel visibility, including J1939 OEM integration, compensated fuel level and distance-to-empty, cylinder pressure, average fuel economy, and engine fuel pressure.
5
Fuel Gauge Module
A-1's proprietary module integrates fuel level data directly with the OEM in-dash fuel gauge and our A-1 InSight gauge.
6
Remote Fuel Management Panel
Centralizes fueling and system components in an accessible, protected enclosure for easier operation and service. A proprietary fuel manifold reduces potential leak points, while integrated starter-interrupt functionality helps protect against drive-offs while connected to a fueling station.

Engineered for the Real World
Every A-1 fuel system is designed around the demands of commercial fleets—from installation and vehicle integration to daily operation, service, and long-term reliability. Our systems combine thoughtful engineering with decades of hands-on alternative fuel experience to deliver solutions built to perform in the field.
Safety by Design
Safety starts at the engineering stage. A-1 systems are designed around applicable industry and vehicle requirements, with careful consideration given to component protection, mounting, fuel management, and real-world vehicle operation.
Optimized Capacity
Multiple configurations allow fleets to balance fuel capacity, range, available frame space, and vehicle weight to find the right solution for each application.
Fleet-Proven Experience
Decades of alternative fuel experience and thousands of vehicle deployments have given A-1 an understanding of what works beyond the drawing board. That experience is built into the way our systems are designed, manufactured, installed, and supported.
Built for Integration
Our systems are engineered around the vehicle—not simply added to it. Flexible mounting, OEM integration, and application-specific configurations help simplify installation while preserving the functionality of the chassis and body.
Designed for Service
Accessible components, service panels, centralized fuel management, and thoughtful system layouts help make inspection, diagnostics, and routine maintenance easier throughout the life of the vehicle.
Support Beyond Installation
Our involvement doesn't end when the vehicle leaves the facility. A-1 provides technical support, replacement parts, system service, and ongoing expertise to help keep fleets operating for years to come.
