1. Black Poly Underbody Truck Tool Box

When you’re looking for a truck underbody toolbox, you’ll most likely discover that a lot of them are aluminum. If you live near a coast with a lot of salty air, such materials are less than ideal. That’s why you may like the look of this truck underbody toolbox from Buyers Products.

Even though it functions the same as aluminum models, it incorporates high-density polyethylene instead. It’s as strong as aluminum but won’t succumb to the elements as severely. Both the door and lid also have a double-wall setup, meaning they are far stronger than one layer of polyethylene alone.

However, that’s not all that’s different and intriguing about this truck underbody toolbox. It features a robust and recessed three-point locking latch, stainless-steel compression, and a drop door. Everything will be safe and secure in this truck underbody toolbox. It doesn’t dent, rust, rot away, or do anything it shouldn’t. Instead, you can install it with ease on the underbody of your pickup then load it full of items you want to keep secure.

If there were anything to complain about, it would be the weather stripping. Before long, you may need to replace it. It can perish quickly, removing the weather resistant components and letting moisture into your truck underbody toolbox.

  • Dent-resistant
  • High-density polyethylene
  • Double-wall door

Considerations for Purchasing a Truck Underbody Tool Box

If you’re tired of your tools of the trade taking up room in your pickup truck, then you may wish to consider buying a truck underbody toolbox. Unfortunately, it can be quite a significant investment, with a lot of room for disappointment as well. Take note of these points below before you get your wallet out.

  1. Size

    Think about all the tools you have piled in the back of your pickup truck. You can’t pick any truck underbody toolbox and hope it will do the trick. Put your tools into a pile and measure them. You can then compare those measurements to one of the many boxes on the market to make sure you have plenty of room to spare.

  2. Construction

    Most truck underbody tool boxes take a hammering – all because they are out in the elements all the time. Don’t settle for less than the best materials. Aluminum is strong, lightweight and durable,and polyethylene is an excellent substitute if you prefer it to metal.

  3. Price

    Finally, think about how much you want to spend. Set a budget and stick to it. Truck underbody tool boxes vary by hundreds of dollars, but the quality doesn’t deviate to the same degree. It’s okay to opt for the most affordable truck underbody toolbox on the market but ensure the quality and features are on par with other more expensive options.

  4. Weather

    Because your truck underbody toolbox is going to spend most of its time outside, weather-proofing is a must. Bare steel will rust away without protection, and if you don’t have the best gasket seals, your tools and items will get wet too. Read the reviewer comments and make sure the box you pick will handle all weather.
