Go Farther Every Time You Fill Up

Running out of fuel sooner than expected can interrupt a job, delay a trip, or force an extra stop when you would rather keep moving. The S&B 10-1035 50 Gallon High-Capacity Fuel Tank gives your 2005-2026 Dodge Ram 2500 or 3500 Crew Cab Short Bed with the 5.9L or 6.7L Cummins diesel engine the freedom to travel much farther between fill ups. By replacing the factory 31 gallon tank with an approximately 50 gallon design, you gain about 19 additional gallons of fuel capacity without sacrificing the convenience of a direct bolt on installation. Additionally, S&B takes advantage of unused space beneath the truck, turning wasted room into practical fuel storage that works for you every mile of the journey. Fewer stops at the pump means more time on the road whether you are towing, traveling across the state, or putting in long hours at the jobsite. The added range can also make remote destinations much more manageable by reducing the need to search for fuel along the way. It is a practical upgrade that delivers real benefits every time you climb behind the wheel.

Designed To Maximize Capacity Without Compromising Performance

The S&B 50 Gallon High-Capacity Fuel Tank is engineered to provide increased fuel capacity while maintaining reliable operation with your truck's factory fuel system. Constructed from 1/4 inch thick cross linked high density polyethylene, this tank offers greater impact resistance than the factory linear polyethylene tank, making it well suited for demanding work and off pavement travel. Furthermore, it is designed for compatibility with high flow diesel pumps, allowing for fast and consistent refueling without premature nozzle shutoffs or messy overflows. The tank reuses the OEM sending unit and includes the necessary mounting straps for installation, creating a straightforward replacement for the original fuel tank. Because the tank is taller than stock, the factory fuel gauge will remain on full during the first 8 to 10 gallons of fuel use, and the distance to empty calculation will no longer be accurate. Ground clearance is reduced by approximately 2 to 3 inches compared to the factory tank, and it is not compatible with the OEM skid plate. Best of all, this upgrade is street legal in all 50 states, giving you confidence to enjoy the added capacity wherever the road takes you.
