Cummins High-Capacity Fuel Tanks

S&B’s high-capacity replacement diesel fuel tanks deliver fewer stops and more miles for Ram trucks with a Cummins engine from 2005 to present.

Available Fuel Tank Sizes: 52, 55 & 60 Gallons

Increase fuel capacity and distance between refueling with S&B’s high-capacity fuel tanks custom designed for Ram trucks with Cummins engines. From 52 to 60 gallons, our tanks match your model year, cab and bed length to significantly increase fuel capacity by maximizing all available undercarriage space. Built with durable cross-linked polyethylene and heavy-duty stainless-steel straps, our tanks are bigger and stronger than stock tanks.

Compatible with Ram 2500 & 3500 Cummins 5.9L & 6.7L

S&B replacement fuel tanks fit seamlessly into Cummins trucks, including Dodge Ram 2500 and 3500’s from 2005 to 2024 covering crew, quad, and mega cabs as well as short and long bed configurations. Our high-capacity tanks install easily without having to modify or relocate surrounding parts. Plus, the OEM sending unit is preserved so your fuel gauge will remain accurate.
