Maximize your truck’s true potential and significantly reduce your time spent at the pump with the S&B 10-1035 High-Capacity Fuel Tank. Engineered specifically for 2005–2026 Dodge Ram 2500 and 3500 trucks equipped with the 5.9L or 6.7L Cummins engine (Crew Cab and Quad Cab Short Bed configurations), this premium midship replacement tank is a masterclass in efficient utility. By using advanced scanning technology to claim the vast, unused space beneath your truck's undercarriage, S&B replaces the restrictive 31-gallon factory tank with an expansive 52-gallon reservoir. This immediate 68% increase in fuel capacity effectively pushes your driving range toward the 1,000-mile mark, giving you the freedom to bypass expensive highway fuel stops and travel further on your own terms.
- 52-Gallon Capacity: Gain an extra 21 gallons of fuel over stock, vastly extending your driving range and reducing refueling frequency.
- Superior XLPE Construction: Manufactured from 1/4-inch thick cross-linked high-density polyethylene, offering vastly superior impact resistance and off-road durability compared to standard linear polyethylene factory tanks.
- Direct Bolt-In Installation: Engineered as a straightforward swap that requires absolutely no vehicle modifications, coming complete with new heavy-duty mounting straps.
- Factory Integration: Designed to seamlessly reuse your truck's original factory sending unit, ensuring accurate fuel gauge readings and reliable performance.
- High-Flow Pump Compatibility: Features optimized venting to eliminate premature shutoffs and messy overflows, allowing for fast, uninterrupted fills even at high-volume commercial diesel pumps.
- Limited Lifetime Warranty: Backed by S&B's robust manufacturer warranty, giving you long-term peace of mind on every journey.
Beyond the undeniable convenience of fewer pit stops, the S&B High-Capacity Fuel Tank represents a fundamental upgrade in vehicle self-reliance and longevity. Choosing a high-capacity replacement over auxiliary bed tanks preserves your valuable cargo space while keeping the center of gravity low and safely integrated into the chassis. Whether you are towing heavy payloads across state lines, navigating remote off-road trails, or simply seeking the peace of mind that comes with a massive fuel reserve, this tank delivers the resilience and engineering your Cummins demands. Upgrade today to transform empty undercarriage space into pure, uninterrupted driving freedom.
Note:
- 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
