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.

Always order big!
I needed a minimum of 2 AWG wire to create interconnects between batteries in a large bank. If you note, these say 1/0 Gauge, not AWG. What is 1/0 Gauge? Who knows, it's fake. Meaningless, because it is not standardized so you have no clue what you are getting. What did I get for my 1/0 Gauge wire? Something that was in between 1 and 2 AWG (closer to 1). This was perfect for my needs because I knew darn well how big to order when they say gauge instead of AWG. As a rule of thumb: If they as gauge, order 3 - 4 sizes larger than you need in AWG. This will always net you larger wire than you need but I have never had it net me wire smaller than I needed. At the price I got it for during prime days, it was a steal for 2 AWG wire, so I win! I hope you found this helpful!

Heavy duty and has lasted three years so far
I have had this relay installed in the engine bay of my Lexus RX 300, functioning to link the front battery to the additional battery in the trunk whenever the ignition is on. The relay has worked reliably for about three years now with no complaints besides one minor comment, be careful when threading down the nut on the Low voltage side. It is prone to stripping

Heavy Duty!!
Performed extremely well. No buzzzing or poor connection. Extremely well built and has been working issue free for over 6 months! Instalation can be a bit difficult due to size and weight. Not really a problem.

Seems to be ok for the money
We use it to power a 2000w inverter for the refrigerator and microwave on our boat where sometimes it will stay on continuously throughout the day and it hasn't let us down. As others have said, the terminals are awful close together but for the money, it's worth it.
