Upgrade the limited factory fuel capacity on your 2013-2026 Ram 2500 or 3500 6.7L Cummins Crew Cab Long Bed with the S&B 56 Gallon High-Capacity Fuel Tank. Designed as a direct bolt-on replacement for the factory 31-gallon tank, this premium replacement tank nearly doubles your fuel capacity so you can spend more time on the road and less time searching for fuel stations.
Constructed from heavy-duty cross-linked high-density polyethylene (XLPE), the S&B fuel tank offers superior durability and impact resistance compared to the factory tank. Internal anti-slosh baffles help keep fuel around the pickup while reducing unwanted fuel movement and noise during towing, off-road driving, or daily use.
The S&B 56 Gallon Tank is engineered specifically for 2013-2026 Ram Cummins Crew Cab Long Bed trucks and maximizes unused space underneath the truck without major modifications. This direct-fit design reuses the OEM sending unit and installs using factory mounting locations for a clean installation.

NEARLY DOUBLE THE CAPACITY
The S&B 56 Gallon High-Capacity Fuel Tank is a direct replacement for the 31 gallon factory tank. With 25 more gallons of fuel available, the S&B tank allows you to travel over 1,000 miles between fill ups, whereas the smaller stock tank will only get you about 600 miles. Enjoy the freedom, flexibility and time saved with a significantly bigger tank.
"NO SLOSH" TANK DESIGN
S&B tanks are engineered with built-in baffles to minimize fuel sloshing. This innovative design ensures fuel stays around the pick up and prevents unwanted tank sloshing noise.
STRONGER THAN STOCK
Made with 1/4" thick cross-linked high density polyethylene (XLPE), the S&B tank has significantly more impact strength than the OEM linear polyethylene tank. This is a big advantage when trekking offroad.
HI-FLOW NOZZLE COMPATIBLE
This high-capacity fuel tank works seamlessly with the high-flow fuel pumps found at truck stops and is engineered to handle rapid fueling without premature shut off or causing overflow. With its optimized venting, fill-ups are smooth and hassle-free allowing you to get back on the road quickly.
USE ALL THAT WASTED SPACE
It's shocking how much empty space there is underneath the 2013+ 6.7L Cummins Crew Cab Long Bed. S&B's advanced scanning technology and industry-leading tank manufacturing turns all that wasted space into 25 extra gallons of diesel carrying capacity so you travel further on one tank than you ever thought possible.
