"More Trailer For Your Money"

7 x 26 Diamond C HDT-GN 307 24K Tilt Trailer – Ready To Work!

The HDT-GN 307 is Diamond C’s powerhouse triple-axle tilt trailer. The "307" designation identifies the triple 7,000 lb axle configuration, placing this unit in a 24,000 lb GVWR class. It is the premier choice for operators who need the massive payload of a dual-tandem trailer but prefer the lower deck height, smoother towing, and improved weight distribution of a triple-axle setup.

Triple 7,000 lb Torsion Axles The standout feature is the three 7,000 lb Lippert Torsion axles. Unlike traditional leaf springs, torsion axles provide independent suspension for each wheel.

• The Benefit: This creates a much smoother ride for your equipment, better tracking at highway speeds, and ensures that if you hit a pothole, the shock isn't transferred across the entire frame.

24,000 lb GVWR & Engineered Beam To handle 12 tons of gross weight, Diamond C uses its patented Engineered Beam frame. These beams are custom-fabricated in-house to be taller and stronger at the pivot points while remaining lightweight. This design maximizes your legal payload and prevents the "sagging" common in standard I-beam trailers.

Hydraulically Dampened Gravity Tilt This system uses a heavy-duty cushion cylinder to control the bed’s movement. You simply unlatch the deck and drive your equipment on; the weight of the machine smoothly transitions the bed back to the hauling position. A speed-control valve allows you to adjust the tilt rate based on the weight of your load.

Fleetneck 2.0 Curved Neck The gooseneck features Diamond C's signature curved design. By using a one-piece fabricated neck and eliminating 90-degree corner welds, the design removes the most common stress-fracture points found in traditional goosenecks.

14-Ply All-Steel Radial Tires To support the 24k rating, the 307 comes standard with ST235/80R16 14-ply tires. These are commercial-grade radials designed to handle the heavy vertical loads and the lateral "scrub" that occurs with triple-axle configurations during tight turns.

Full-Width Diamond Plate Neck Box The gooseneck includes a massive storage box integrated between the uprights. It features a gas-shock assisted lid and offers ample room for chains, binders, and tools, keeping your deck clear for cargo.

Warranty 2.0 Every HDT-GN 307 is backed by Diamond C’s updated warranty suite, featuring a 6-year structural warranty, 3-year paint warranty, and a 2-year comprehensive warranty on components. Additionally, the torsion axles carry an industry-leading 11-year axle warranty.

PERFECT FOR

The HDT-GN 307 is ideal for heavy excavation, paving, and agricultural crews. It is specifically designed to haul large skid steers with heavy attachments, mid-sized excavators, and wide-axle tractors. The triple-axle design provides incredible stability at highway speeds and ensures that even if you have a flat tire, you still have four tires on the ground to get safely to the shoulder.

WHY CHOOSE THE HDT-GN 307 OVER THE COMPETITION

The "Triple Torsion" AdvantageWhile many competitors use triple leaf-spring axles to save cost, Diamond C standardizes Triple 7,000 lb Torsion Axles on the 307.

• The Competition: Uses leaf springs which can lead to "axle hop" and a bouncy ride when empty.
• Diamond C: Torsion axles provide independent suspension for all six wheels. This results in a "velvet" tow, significantly less vibration for your sensitive electronics on heavy machinery, and an industry-leading 11-year axle warranty.

Patented Engineered Beam FrameMost brands buy "off-the-shelf" I-beams from a steel mill. Diamond C is one of the only manufacturers that fabricates their own beams in-house.

The Competition: Standard I-beams are the same thickness from front to back, adding "dead weight" where it isn't needed.

• Diamond C: The beams are taller and stronger at the critical pivot point of the tilt bed and tapered where they don't need the bulk. This creates a trailer that is stronger yet lighter, allowing you to carry more legal payload than a competitor’s heavier trailer.

**Fleetneck 2.0 (Curved Neck Design)**Look at the gooseneck of any other brand: you will see two I-beams welded at a sharp 90-degree angle with a "gusset" plate.

• The Competition: 90-degree welds are the #1 failure point where frames crack under heavy torsion.
• Diamond C: Uses a single-piece, curved engineered neck. By eliminating the corners, they eliminate the stress concentration points. It’s a design borrowed directly from high-end semi-trailers.

Precision Hydraulic DampeningA 24,000 lb trailer carries massive equipment that can be dangerous if the tilt bed slams down.

• The Competition: Often uses cheap, single-speed cylinders that can "crash" the bed down if the machine isn't perfectly balanced.
• Diamond C: Features a heavy-duty dampening cylinder with an
