"More Trailer For Your Money" 7 x 16 Diamond C LPT-GN 307 24K Dump Trailer – Ready To Work! 14 Ply Tires, Board Brackets

The Diamond C LPT-GN 307 is the extreme-capacity triple-axle powerhouse of the gooseneck dump lineup. By utilizing triple 7,000 lb axles, this trailer reaches a massive 24,000 lb GVWR, offering superior weight distribution and a smoother ride than tandem-axle models. This configuration is the ultimate "float" trailer—designed to carry maximum payloads across soft job sites and long highway stretches with unmatched stability. CORE FEATURES OF THE LPT-GN 307 Triple 7,000 lb Slipper Roller Axles (24K GVWR) The "307" designation indicates the shift to three 7k axles rather than two heavy axles. The Benefit: Spreading 24,000 lbs across six tires instead of four reduces the "point load" on any single hub or tire. This provides a more stable towing experience, better tracking on the highway, and ensures that if you have a flat tire, you still have two supporting axles on that side to safely get you off the road. 3-Stage Front-Mount Telescopic Cylinder The LPT-GN 307 features the signature telescopic hoist at the extreme front of the bed. The Benefit: At a 24k rating, leverage is everything. Pushing from the front of the body is the most efficient way to lift 12+ tons of material. It puts significantly less stress on the main frame compared to a scissor lift and handles unevenly distributed loads without the frame-twisting risk. 12" Curved Engineered Gooseneck This model utilizes Diamond C’s patented curved engineered neck design. The Benefit: Standard gooseneck necks have 90-degree welds that concentrate stress and are prone to cracking over time. The curved design flows that stress through the entire neck, making the trailer lighter yet significantly stronger for high-frequency commercial use. 8" x 15 lb I-Beam Main Frame The chassis is built on a high-strength 8" I-beam foundation, engineered to resist the torque of triple-axle turns. The Benefit: This provides a rigid, low-profile base. By keeping the center of gravity low, the 307 remains stable at highway speeds and offers a shallower loading angle for heavy machinery. Integral Body The body features the floor and sides formed as a single integral unit. The Benefit: By forming the floor and sides together, Diamond C eliminates the bottom corner seam. This prevents debris and moisture from getting trapped in the corners, which is where rust usually starts on traditional dump trailers. Dual 12,000 lb Drop-Leg Jacks Standard equipment includes two side-crank 12,000 lb jacks located in the gooseneck. The Benefit: With a combined 24,000 lb static capacity, these jacks provide a rock-solid foundation when unhooked. The drop-leg feature allows you to quickly adjust the jack height without the manual labor of endless cranking. 3-Way Dump Gate & HD 78" Slide-In Ramps The 307 comes standard with the 3-way gate (Spreader/Barn/Truck) and 3" I-beam ramps. The Benefit: You can spread gravel like a pro or swing the doors wide for bulky demolition debris. The heavy-duty ramps allow the LPT-GN 307 to double as a high-capacity equipment hauler for machines up to 12,000 lbs. THE TRIPLE-AXLE TITAN WHY THE 2026 LPT-GN 307 IS THE ULTIMATE LOW-PROFILE DUMP When dual axles aren't enough, move up to the Triple-Axle 307. It is the most stable, high-capacity gooseneck dump on the market, built to bridge the gap between a standard trailer and a semi-dump. THE STABILITY: Triple 7k Slipper Roller Axles Experience the smoothest tow in the industry. Our triple-axle setup distributes weight more evenly, reduces tire wear, and provides a "floating" ride that protects your truck and your cargo. THE NECK: Patented 12" Curved Engineering We eliminated the stress points that cause other goosenecks to fail. Our one-piece curved neck is stronger, lighter, and more durable, ensuring your investment lasts as long as your business does. THE HOIST: Front-Mount Telescopic Power Don't let your hoist stall out. Our 3-stage telescopic cylinder pushes from the front of the bed for maximum leverage, dumping a full 24,000 lb load at a steep 45-degree angle every single time. THE STORAGE: Massive Integrated Neck Box Keep your job site organized. The full-width diamond plate neck box provides massive, lockable storage for chains, binders, and tools, keeping your truck bed clean and your gear secure. PERFECT FOR The LPT-GN 307 is built for high-volume commercial contractors and demolition crews who require the absolute maximum payload possible in a gooseneck dump. It is the go-to for professionals hauling heavy machinery or massive loads of rip-rap and debris who value the superior stability and weight distribution of a triple-axle setup.
