Why We Like Aluminum Service Bodies
When building a mechanics service truck, every pound matters. The body itself is one of the largest contributors to a truck’s curb weight, so choosing an aluminum service body can make a significant difference in how the truck performs and what it can carry.
At Arrow Equipment, our 11 Series and Brutus aluminum service bodies are designed to maximize payload while providing the durability and functionality that mechanics rely on every day.
More Payload Means More Possibilities
One of the biggest advantages of an aluminum body is the weight savings.
Depending on the size and configuration, an aluminum mechanics service body is typically 700 to 1,500+ pounds lighter than a comparable steel body. Some larger crane bodies can save even more—approaching 2,000 pounds in certain configurations.
That extra payload can be used for equipment that actually makes money instead of simply carrying the truck body itself.
For example, the available weight savings may allow you to add:
- A larger crane with higher lifting capacity
- A larger VMAC or air compressor system
- A waste oil recovery system
- Additional fuel or DEF tanks
- More tooling and parts
- Larger generators or welders
- Extra accessories without exceeding your GVWR
Instead of sacrificing storage space or payload, you gain flexibility to build the truck around your work.
Keep All Your Storage
As service trucks become more specialized, operators are adding more equipment than ever before.
An aluminum body helps make room for those additions while keeping the storage you’ve come to rely on.
That means:
- Full-height cabinets
- More drawer packages
- Better organization
- Room for specialized tools
- No need to leave equipment behind because of weight limitations
Built to Resist Corrosion
Unlike steel, aluminum doesn’t rust.
For fleets operating year-round, especially on roads treated with salt, this is a major advantage.
Benefits include:
- Excellent corrosion resistance
- Cleaner appearance over time
- Reduced long-term maintenance
- Better resale value
- Longer service life
While aluminum can still oxidize, it doesn’t experience the same type of corrosion that eventually weakens untreated steel.
Strong Where It Matters
A common misconception is that lighter means weaker.
Modern aluminum service bodies are engineered with reinforced structural components, heavy-duty mounting systems, and crane reinforcement packages designed to handle demanding work environments.
When properly engineered, aluminum provides an excellent balance of strength, durability, and weight savings.
Why We Choose Aluminum
Our 11 Series and Brutus service bodies are built to help customers get the most out of their truck.
Whether you’re installing:
- A Cobra crane
- VMAC compressor
- Welder
- Waste oil system
- Auxiliary power
- Additional lighting and accessories
…the lighter body gives you more flexibility to build the truck you actually need while staying within your truck’s weight rating.
A service truck should work for you—not limit you.
Choosing an aluminum body helps maximize payload, reduce corrosion concerns, and create more room for the tools and equipment that keep your crew productive.
When every pound counts, aluminum gives you more options.
