When it comes to dump bodies, small design decisions add up fast. The wrong cylinder setup, a fixed skirt, a narrow floor radius – these aren’t minor inconveniences. They’re downtime. They’re repair costs. They’re trucks that don’t earn their keep.
Load King dump bodies are manufacturedand engineered around the realities of the job: heavy loads, hard impacts, and equipment that needs to stay in service. Here’s what makes them different.
Cylinders: A Design That Reduces Doghouse Size
Load King dump bodies use a hybrid trunnion cylinder; the big end stays on the bottom, but it’s inverted. The result is no doghouse protruding into the bed. That matters because conventional doghouses are a prime spot for material to pack and stick, especially when you’re hauling rock, gravel, or demolition debris. Less buildup means cleaner dumps and fewer delays.
Body Material and Bolt-On Skirts: Repairability Engineered In
The standard 16×48 model is built with quarter-inch & 3/16” AR450 steel, the kind of material spec that holds up thousands of load cycles. But the design decision that separates Load King from the competition is the bolt-on skirt.
If a loader catches the skirt, you don’t have to cut. You don’t have to weld. You unbolt the damaged panel and replace it. One section or two, it doesn’t matter. The repair stays fast and keeps the truck earning.
Formed Main Runners: Ready for What’s Next
Many manufacturers use rectangular tubing or I-beams for main runners. Load King uses formed main runners that are pre-prepped internally for a heated floor baffle and ready to accept a body vibrator.
That means no cutting, no welding when it’s time to add options. Whether you’re upfitting at the factory or converting into the field, the work is already done. For fleets that need to move fast on configuration changes, that’s a real advantage.
High-Lift Options: Internal and External, Your Choice
Load King offers both internal and external high-lift cylinder configurations. Many manufacturers commit to one or the other; Load King gives customers the choice.
It’s worth understanding the difference: replacing an internal cylinder is a significant job. Replacing an external cylinder takes about ten minutes. For fleet managers thinking about lifecycle maintenance costs, that’s not a small distinction.
Apron: Built Not to Bend
The apron is Schedule 80 quarter-inch AR450 steel with 3-inch Schedule 80 pipe. It’s engineered to withstand the stress of high-cycle loading without yielding. On a body that sees daily abuse, an apron’s integrity is one of the first things to go; Load King’s spec is designed to make sure it doesn’t.
Bed Width and Welding: The 24-Inch Radius Difference
This is one of the standout spec points across all Load King dump bodies. Many competitors run a 12-inch radius from sidewall to floor. Load King runs 24 inches.
What does that mean in practice? When you drop busted concrete, rip rap, or heavy aggregate into the bed, the material has room to slide before it hits the floor. That reduces impact force and the impact force over thousands of cycles is what wears out a body. The wider the radius, the longer the body lasts.
The floor is also overlapped and welded solid to the front. No gaps, no stress points, just structural integrity built into the weld.
Shedding Plates: Clean Dumps Every Time
Strategically placed shedding plates at the base of the body eliminate the corners where material tends to pack and stick. The design mirrors how a slope-front body dumps; everything moves out cleanly, every time. Faster cycle times and no residue building up in the bed.
Standard Features: No Upcharge for the Basics
Every Load King dump body ship with a dirt-shedding top rail ladder, three lights on each side, and a standard 50-ton pintle hitch, included as baseline equipment. These aren’t options. They’re standard. That matters when you’re keeping costs predictable.
Standard Cab Controls: Simple, Intuitive, Always There
Every truck comes with a standard cab control panel: tailgate latch/unlatch, high-lift control, tarp, PTO, and body up/down. Clean layout, no hunting for controls. Operators get in, know where everything is, and stay focused on the work.

FAQ
What makes Load King dump bodies different from other manufacturers? Load King dump bodies are built with several standout features: a hybrid trunnion cylinder that eliminates the doghouse, bolt-on skirts for fast repairs, formed main runners pre-prepped for heated floors and body vibrators, a 24-inch floor radius (double the industry standard), and shedding plates for clean dumps. They’re manufactured by Custom Truck One Source with an emphasis on durability and low lifecycle maintenance costs.
What steel is used in Load King dump bodies? Load King’s standard 1648 model is built with quarter-inch AR450 steel on both the body and apron. The apron also incorporates 3-inch Schedule 80 pipe, engineered to handle high-cycle loading without yielding.
Are Load King dump body skirts easy to repair? Yes. Load King uses bolt-on skirts rather than welded ones. If a skirt panel gets damaged, you unbolt it and replace it, no cutting or welding required. This keeps repair time and downtime to a minimum.
What cylinder options are available on Load King dump bodies? Load King offers both internal and external high-lift cylinder configurations. External cylinders can be replaced in about ten minutes, making them a strong choice for fleets focused on minimizing maintenance time and lifecycle costs.
Who manufactures Load King dump bodies? Load King is the in-house manufacturing arm of Custom Truck One Source (CTOS). Building equipment in-house allows for tighter quality control, faster turnaround, and specs tailored to the industries CTOS serves, including construction, utility, and municipal fleets.
