Titan Fuel Tanks Gen 7 XXL 55 Gallon Mid-Ship Replacement Fuel Tank for 2025 Ram 2500/3500 (Cummins) 7030325
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2025 Ram 2500 and 3500 pickups equipped with the Cummins diesel engine and Crew Cab Long Bed configuration. This Titan Gen 7 XXL tank replaces the factory unit to provide a massive 55-gallon fuel capacity, significantly extending your vehicle's range.
Constructed from military-grade High-Density Cross-Linked Polyethylene (XLHDPE), this tank is engineered for extreme durability and chemical resistance. Unlike metal tanks, it is corrosion-proof and features a low fuel trap design that ensures all 55 gallons are usable capacity. The Gen 7 design allows for a direct-fit, bolt-in installation using factory mounting points, with the bottom of the tank sitting only approximately 2.5 inches lower than the stock tank.
