You've decided to invest in a BRUTE side-rail-mounted toolbox: Will it be a TopSider or a LoSider?
Side rail boxes keep your bed open for drywall, pallets, or even hauling dirt bikes on the weekend. But choosing between side rail box styles comes down to how you use your truck, what you’re hauling, and what kind of profile you want your rig to have. Let's break down the differences so you can make the right call for your setup.
The LoSider: Sleek and Practical
Let’s talk about the BRUTE LoSider first. We have heard some customers state that they underestimated the blind spot some side rail boxes can create. The LoSider completely fixes that problem. It keeps a much lower profile on your bed rails and gives you easily accessible, over-the-rail storage. If you're worried one may not offer enough storage, install two and double the space.
This is the go-to choice for the weekend warrior, the commuter who doubles as a DIYer, or the tradesman who values rear window visibility just as much as tool capacity. It's built with a heavily reinforced top lid, push-button rotary latches, and gas prop supports protected by shields so you can confidently pop the box open with one hand.
The TopSider: The Contractor's Workhorse
Spend any time on a commercial site and you'll see a lot of TopSiders. Standing tall, the TopSider doesn't care about a sleek profile - it's there to hold every single tool you own - and if you double up, you can live out of them.
TopSiders offer multiple door configurations and have an insane amount of storage volume. Built-in drawers and shelves keep everything organized. However, keep in mind that all that storage comes with a rearview-reducing form. Remember that blind spot problem we mentioned earlier? This box is the cause, so be prepared and double-check your mirrors.
Built BRUTE Tough
If you want a clean side rail, zero blind spots, and quick top-down access, go with the LoSider. If you are a heavy-duty hauler and need to carry lots of tools or equipment daily, the TopSider can help.
- Both boxes are proudly Made in the USA from strong, rust-resistant aluminum that can easily handle job site abuse and off-road flex.
- Your gear stays safe thanks to lockable, rust-resistant stainless steel T-handles and latches, and a sleek beveled lid supported by gas-assisted supports for hands-free access.
- The beveled design forces water to roll off, and a full rubber weather seal, combined with an integrated rain gutter, keeps your tools clean and dry.
- A simple, no-drill install with a custom J-hook bracket system is all that's needed to install most boxes - and they're backed by a Limited Lifetime Warranty.
