What Size Underbody Truck Tool Box Do You Need? 36 vs 48 vs 60 Inch

Choosing an underbody truck tool box is mainly a fitment problem: width, depth, height, available mounting space, door clearance, and payload all matter. This guide compares VEVOR aluminum underbody truck boxes in common 36, 48, and 60 inch widths so you can narrow the right configuration before ordering.

Quick answer

Choose a 36 in box when mounting space is limited or you want a compact setup. Choose 48 in when you need more tool capacity without moving to a very wide box. Choose 60 in when your truck or trailer has enough clear mounting width and you need maximum long-item storage. Depth and height matter just as much as width: VEVOR currently offers shallower 14 × 16 in, mid-depth 17 × 18 in, and deep 24 × 24 in configurations.

36 inch vs 48 inch vs 60 inch: what changes?

Width determines how much long-item storage you gain and how much frame space the box consumes. A 36 inch box is easier to fit between structural components. A 48 inch box gives noticeably more horizontal storage while remaining manageable on many trucks and trailers. A 60 inch box works best when the vehicle has a long uninterrupted mounting area.

Do not choose by width alone. A 36 × 24 × 24 in box is much deeper and taller than a 60 × 17 × 18 in box, so the smaller-width model can still consume more vertical and outward clearance.

How to measure before ordering

1. Measure usable width: check the clear span between frame members, brackets, tanks, exhaust parts, suspension components, and tires.
2. Measure depth: confirm the box will not project into a tire path, step, trailer hardware, or other moving area.
3. Measure height: include ground clearance and any door-opening space you need.
4. Check door swing: deeper 24 in boxes can require more room to open fully.
5. Plan mounting brackets: the box and stored load must be supported by an appropriate mounting structure.

Which configuration makes the most sense?

• 36 × 14 × 16 in: best when clearance is tight and you still want a lockable aluminum box.
• 36 × 17 × 18 in: a balanced compact size with more depth and height.
• 48 × 17 × 18 in: a strong middle-ground choice for more capacity without the footprint of a 60 in box.
• 60 × 17 × 18 in: better for long tools and larger maintenance kits when mounting width is available.
• 24 × 24 in depth/height models: best when volume matters more than keeping the box shallow.

Material and weather protection

The compared VEVOR configurations use aluminum alloy construction with a tread-pattern surface. The listings also describe a rubber sealing strip, embedded T-handle, lock, and two keys. These features are intended to help protect tools and equipment during vehicle use, but final weather resistance still depends on installation, seal condition, orientation, and exposure.

FAQ

What size underbody truck tool box should I buy?

Choose the largest box that fits your measured mounting area without reducing required ground, tire, suspension, exhaust, or door clearance.

Is a 48 inch box much larger than a 36 inch box?

It adds 12 inches of width, but overall fit still depends on depth and height. A 36 × 24 × 24 in box can require more clearance than a 48 × 17 × 18 in box in other directions.

What wall thickness do these aluminum boxes use?

The listed configurations use 0.06 inch / 1.5 mm wall thickness.
