Simple Swap for Stock Tank
A straightforward bolt-on installation to get 68% more fuel and pushing 1,000 miles of range. The S&B 50 Gallon Tank utilizes all available unused space in the undercarriage to maximize the utility of your truck.

 
Compatible with High-Flow Pumps
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.

 
Put Empty Space To Work
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 19 additional gallons of fuel capacity—so you can go much farther on a single tank.

 

Stronger By Design
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.
