Construction & Design

The S&B high-capacity fuel tank is crafted from high-grade steel, engineered to withstand the rigors of heavy-duty use and harsh environments.

The tank’s taller design accommodates the increased fuel volume while maintaining a secure fit within the factory mounting points. Precision welding and quality control measures guarantee a leak-free seal and structural integrity under demanding conditions.

Installation & Fitment

Installation is straightforward and requires no modifications to your Ram 2500 or 3500 truck.

The OEM sending unit and float are reused, simplifying the installation process. While the fuel gauge will continue to function, please note that the distance-to-empty calculation will not be accurate due to the increased tank size. Professional installation is recommended to ensure proper fitment and safety.

What's Included

• One S&B 56 Gallon High-Capacity Fuel Tank

• Installation instructions

Ideal For

This high-capacity fuel tank is perfect for Dodge Ram 2500 and 3500 owners who require extended driving range without frequent refueling. It is especially beneficial for:

• Long-distance commercial drivers and fleet operators
• Off-road enthusiasts and overlanders
• Construction and agricultural professionals working in remote areas

Important Notes

The fuel gauge will continue to operate; however, the distance-to-empty readout will not reflect the increased tank size and will be inaccurate. There is currently no method to recalibrate the fuel tank size for accurate distance-to-empty readings. Additionally, if you have an auxiliary fuel tank installed, using it in conjunction with the S&B high-capacity tank will void the product’s lifetime warranty.
