Kenworth W900A Tool & Battery Boxes

Frequently Asked Questions About Kenworth W900A Tool & Battery Boxes

Will a tool or battery box made for the W900A fit my truck without modification?

Most boxes in this category are designed to match the frame width, step configuration, and mounting points found on the W900A, but fitment can still vary depending on your truck's model year, frame rail spacing, and whether you have factory or aftermarket brackets already installed. It's a good idea to measure your existing mounting area and compare it to the listed dimensions before ordering, and to check whether mounting hardware or brackets are included or sold separately.

What materials are these boxes made from, and how well do they hold up over time?

Tool and battery boxes for the W900A are typically available in aluminum or steel construction, sometimes with a diamond plate finish. Aluminum options resist rust and are lighter, making them a common choice for boxes that see road spray and weather exposure, while steel versions offer added strength for heavier tool storage. Look at the listed gauge thickness and finish to get a sense of durability, and keep in mind that unfinished aluminum will develop a natural patina over time unless it's polished or coated.

Are these boxes designed to carry batteries, tools, or both?

It depends on the specific box. Battery boxes are usually built with dedicated compartments sized for standard truck battery groups and often include vented lids or drain provisions, while tool boxes are typically open storage or divided compartments meant for tools, chains, and other equipment. Some combination units offer both a battery compartment and separate tool storage in one unit, so check the product description to confirm which configuration you're getting.

What should I check before installing a new box myself?

Before installation, confirm the box includes the mounting brackets, hardware, or straps needed for your frame setup, and verify the hole pattern lines up with your existing mounting points or that you're prepared to drill new ones. If you're replacing a battery box, make sure the compartment size and cable routing will accommodate your current battery group size and existing wiring without excessive modification.

Do these boxes come with a lock or latch, and can I add my own?

Many tool and battery boxes come with a basic latch, T-handle, or paddle-style closure, and some include keyed locks while others do not. If security is a priority, check the specific listing to see what's included, since aftermarket locks or latch upgrades can often be added afterward if the box doesn't come with one you're satisfied with.
