Increase your driving range with the S&B 52 Gallon High-Capacity Replacement Fuel Tank, designed for 2025–2026 Dodge Ram 2500 and Ram 3500 trucks equipped with the 6.7L Cummins Turbo Diesel engine, Mega Cab, and Short Bed configuration.

Replacing the factory 31-gallon fuel tank, this high-capacity upgrade provides 21 additional gallons of diesel storage, increasing fuel capacity by approximately 68%. Enjoy fewer fuel stops, greater convenience on long-distance drives, and an extended driving range for work, towing, and travel.

Constructed from rugged cross-linked high-density polyethylene (XLPE), the S&B fuel tank is engineered for long-lasting durability and dependable performance. Its replacement design provides increased fuel capacity while utilizing the available space beneath your truck.

Product Features

• 52-Gallon Fuel Capacity: Increases the factory 31-gallon capacity to 52 gallons.

• 21 Additional Gallons: Provides approximately 68% more fuel capacity than the original tank.

• Direct Replacement Design: Replaces the factory fuel tank on compatible trucks.

• Durable XLPE Construction: Manufactured from rugged cross-linked high-density polyethylene for lasting durability.

• Extended Driving Range: Helps reduce fuel stops during long trips, work applications, and towing.

• Factory Sending Unit Compatibility: Reuses the original equipment manufacturer (OEM) fuel sending unit and float.

Important Notes

• The factory fuel gauge will function normally; however, the distance-to-empty reading will be inaccurate because the vehicle cannot be recalibrated to reflect the increased fuel tank capacity.

• The OEM fuel sending unit and float must be reused. Because the S&B tank is taller than the factory tank, the fuel gauge will remain on full for approximately the first 8–10 gallons of fuel consumed.

• Using an auxiliary fuel tank with the S&B tank will void the S&B Lifetime Warranty.
