Product description
High-Capacity Freedom: Upgrade to 40 Gallons
Break free from the limitations of a small factory tank. The S&B 40-Gallon Replacement Tank offers a massive 66% increase in fuel volume, swapping out your restrictive 24-gallon OEM unit for a long-distance powerhouse. By intelligently utilizing the space between the transfer case and extending 5.2 inches rearward, we’ve engineered a way to carry significantly more fuel without needing to modify your truck's chassis.
Precision Monitoring & Massive "Hidden" Range
We’ve designed this tank to work in harmony with your factory electronics so you can drive with confidence:
Reliable Fuel Gauge: Your dashboard gauge remains fully functional. Due to the expanded capacity, the needle will stay on "Full" for the first 5–7 gallons before moving normally through the rest of the tank.
Extended Reserve: Your "Distance to Empty" (DTE) will continue to calculate based on the original 24-gallon logic. This means if you're averaging 20 MPG, your truck might show 480 miles to empty when your actual range is a staggering 800 miles. You'll always have a massive reserve of miles that the computer doesn't even see.
Industrial-Strength Construction
This tank is overbuilt to handle the most punishing road conditions and environments.
Indestructible Build: Crafted from 1/4” thick Crosslink Polyethylene (PEX), our tanks are naturally resistant to impacts, debris, and extreme temperature swings.
Corrosion-Proof: Unlike steel or aluminum, PEX will never rust, rot, or delaminate, ensuring your fuel stays clean for the life of the vehicle.
Lifetime Warranty: We stand behind our quality with a limited lifetime warranty—this is the last fuel tank your truck will ever need.
True Plug-and-Play Setup
We believe an upgrade should be simple and professional.
Complete Kit: We include all the heavy-duty straps and hardware needed to remove your old tank and secure the new 40-gallon unit.
No Modifications: This is a true bolt-on installation. There is no cutting or drilling required, preserving the integrity of your truck.
Stock Mounting: Designed to fit perfectly in the factory location for a clean, rattle-free installation.
Spend less time searching for a station and more time reaching your destination. Save time, go further, and get more out of your truck with S&B.
