S&B Tanks | 2005-2026 Dodge Ram 5.9L / 6.7L Cummins Crew / Quad Cab Short Bed 52 Gallon Fuel Tank

Extend driving range on 2005–2026 Ram Cummins 5.9L & 6.7L Crew Cab Short Bed trucks with S&B’s 52-gallon high-capacity fuel tank. This direct, bolt-on upgrade replaces the factory 31-gallon tank for fewer stops and more freedom.

Important Notes:

• The fuel gauge will continue to work however the distance to empty will not be accurate. There is no way to update the fuel tank size for the distance to empty to be accurate.
•  OEM sending unit & float are reused. Because the S&B Tank is taller the gauge will stay on full for the first 8-10 gallons 

A straightforward bolt-on installation to get 68% more fuel and pushing 1,000 miles of range. The S&B 52 Gallon Tank utilizes all available unused space in the undercarriage to maximize the utility of your truck.

Built for use with high-flow diesel pumps, this S&B High-Capacity Fuel Tank is engineered for fast, uninterrupted fills—no premature shutoffs or messy overflows. Optimized venting ensures smooth, hassle-free fueling so you can fill up quickly and get back on the road.

There is a lot of unused space sitting beneath the 5.9L & 6.7L Cummins Crew Cab Short Bed trucks. Using advanced scanning and industry-leading tank design, S&B transforms that void into 21 additional gallons of fuel capacity—so you can go much farther on a single tank.

Constructed from 1/4" thick cross-linked high-density polyethylene (XLPE), the S&B tank delivers superior impact resistance compared to the factory linear polyethylene tank—giving you added durability and confidence when heading off-road.
