"More Trailer For Your Money"
8.5 x 40 Diamond C FMAX 210 25K Equipment Trailer – Ready To Work!
Max Ramps
The Diamond C FMAX 210 is the "Gold Standard" of high-end goosenecks, representing the entry point into their heavy-duty tandem dual series. While other manufacturers use standard hot-rolled I-beams, the FMAX 210 is built using Diamond C’s patented Engineered Beam technology, making it stronger, lighter, and more efficient than anything else in the 25,000 lb GVWR class. KEY STANDARD FEATURES Dual Wheel & Tire Package
To support its heavy payload, the FMAX210 comes standard with a tandem dual-wheel configuration.
MAX Ramps System
These are 44" wide, spring-assisted ramps that provide a "dual-purpose" deck. They can be pinned upright for equipment or folded flat to the dovetail. When flat, they create a seamless, full-width loading floor, allowing you to haul hay, pipe, or long lumber over the entire length of the trailer.
16" Engineered Beam 2.0
Diamond C uses a Grade 100 steel frame. Instead of a standard heavy I-beam that is the same thickness throughout, this beam is "engineered"—it's taller and thicker at the high-stress points (the neck and axles) and thinner where it isn't needed, allowing the trailer to be stronger yet lighter than traditional builds.
Heavy-Duty Slipper Roller Suspension
The 2026 FMAX210 utilizes a slipper roller spring suspension system. The "roller" design allows the springs to move more freely, significantly reducing the "chatter" and vibrations felt in the truck when the trailer is empty, while providing superior stability when fully loaded.
Curved Engineered Gooseneck
The 12" gooseneck is constructed with a curved web design rather than sharp mitered corners. This distributes the towing stress across a larger surface area of the steel, preventing the structural cracks common in traditional gooseneck designs after years of heavy use.
Integrated Accessibility (Steps & Lighting)
Safety and ease of use are prioritized with two specific features:
Under-Frame Spare Mount with Winch
Rather than taking up space in the neck or on the deck, the spare tire is stored under the trailer frame. It includes a retractable cable winch system, allowing you to lower the heavy dually wheel to the ground with a simple handle, saving you from heavy lifting during a roadside tire change.
PERFECT FOR Given the heavy-duty construction and the specific MAX Ramp setup, the Diamond C FMAX210 is a "jack-of-all-trades" for high-capacity hauling. It bridges the gap between a dedicated equipment hauler and a flatbed.
Here is why it's perfect for three specific types of users:
Equipment & Machinery Movers
Because of the MAX Ramps, this trailer is ideal for hauling heavy, wide-track machinery like:
"Hot Shot" Trucking & Logistics
The FMAX210 is a staple for commercial hot shotters for several reasons:
Construction & General Contractors
For large-scale projects, this trailer acts as a mobile base:
