The Lamar FS (Gooseneck Flatbed) is Lamar’s flagship "Professional Grade" deckover. Positioned as the ultimate workhorse for hotshotters and heavy equipment haulers, the FS is built to compete with the biggest names in the industry by offering a high-tensile, lightweight frame that maximizes legal payload without sacrificing structural rigidity.

It is designed for the high-mileage user who needs a trailer that can handle massive cargo loads day in and day out.

CORE FEATURES OF THE LAMAR FS

12" @ 19lb (or 22lb) I-Beam Frame & Neck Lamar utilizes a continuous I-beam construction where the neck and frame are integrated for maximum strength.

  • The Benefit: By using a heavier pound-per-foot I-beam than most "economy" competitors, Lamar ensures the trailer resists "the sag" when loaded to its maximum GVWR. The neck is gusseted at every critical stress point to prevent cracking during high-torque maneuvers.

Pierced-Beam "Low-Pro" Design The 3" channel crossmembers are "pierced" through the web of the main I-beam rather than sitting on top of it.

  • The Benefit: This lowers the deck height to approximately 32"–33". A lower deck means a lower center of gravity for better highway stability and a shallower loading angle, making it much safer to load top-heavy equipment.

5' Versa-Ramp System The FS often comes spec'd with Lamar's signature Versa-Ramps—extra-wide, spring-assisted flip-over ramps.

  • The Benefit: These ramps are nearly the full width of the trailer. When folded down, they provide a massive surface area for wide-track machines. When folded flat onto the dovetail, they create a full-length flat deck for hauling hay, pipe, or lumber.

Under-Frame Bridge & Torque Tube (Standard on 30'+) On longer models, Lamar includes a structural bridge under the frame and a heavy-duty torque tube.

  • The Benefit: This prevents the trailer from "twisting" or "bowing" under concentrated loads. If you are hauling a heavy piece of machinery that sits in the middle of the deck, the bridge and torque tube distribute that stress throughout the entire frame.

Dual Dexter® Oil-Bath Axles The FS features the "Gold Standard" of running gear, ranging from 7K axles up to heavy-duty tandem duals.

  • The Benefit: These axles are designed for 100,000+ mile lifespans. The oil-bath hubs make maintenance simple (you can see the oil level through a clear cap), providing the footprint needed for massive payloads and exceptional braking power.

Deca-Shield™ Anti-Corrosive Powder Coat Lamar uses a specialized 6-step finishing process including a sandblast prep and a zinc-rich primer.

  • The Benefit: This is one of the most durable finishes in the industry. It is designed to resist the "sandblasting" effect of road debris and prevents rust from spreading if the trailer is dinged or scratched on a job site.

THE FS QUICK SPECS
  • GVWR: 15,680 lbs (Standard) up to 30,000 lbs.

  • Payload: ~10,000 lbs to ~21,000 lbs (depending on axle and frame configuration).

  • Crossmembers: 3" Channel on 16" Centers (12" Centers optional).

  • Tires: ST235/80R16 Radial Duals (10-Ply) or 17.5" 16-Ply (Recommended Upgrade).

  • Tie-Downs: Stake Pockets, Rub Rail, and Pipe Spools every 2 feet.

  • Toolbox: Lockable full-width neck toolbox for chains and binders.

WHY THE LAMAR FS OVER THE COMPETITION?
  • The "Lamar Lean" Frame: Lamar's engineering focuses on a "high-strength-to-weight" ratio. Their trailers are often a few hundred pounds lighter than some competitors, giving you more legal payload on your specific setup.

  • Pipe Spools: Unlike many trailers that just have stake pockets, Lamar includes pipe spools between every pocket. This adds significant strength to the rub rail and gives you more secure points for hook-end ratchet straps.

  • Commercial Reliability: Lamar has a reputation for "no-nonsense" builds—they don't use flashy plastic end caps or gimmicks; they focus on thick steel and high-quality welds.
