NEW FLEETNECK 2.0 FEATURES

FMAX 2.0 Neck

New, Lighter Neck

The Fleetneck 2.0 neck web is stronger and lighter with the new 10-gauge Grade 80 material resulting in a 65-pound weight reduction.

New Spare Mount Location

The new spare tire mount location with the easy-to-handle winch that raises and lowers the spare is now located under the trailer deck, guaranteeing it is out of your way until you need it.

Grade 100 Beams

Grade 100 main frame beams with a 10-gauge thickness have doubled the yield strength of the Fleetneck 1.0.

Chain Tray/Winch Mount

Storing your chains is easy with the standard chain tray with a winch mount combination and has the option to add a bolt-on winch box.

Engineered Beam Technology

We design, engineer, and build our own I-Beams. Our U.S. Patent Protected Engineered Beam design allows for the tallest and strongest beams in the industry, with the best strength-to-weight ratios on the road.

Taller beam. Lighter Weight. Stronger Frame.

FMAX Overview Diagram
  1. The Neck – Curves distribute force throughout the neck so there is no concentration of stress in corners like traditional goosenecks.
  2. The Deck – It’s low profile for easy access. Tire-covers are HD 3/16” diamond plate. Boards are capped at each end of the deck for added durability.
  3. The Camber – The deck and frame have a slight camber when not loaded. When loaded, it flexes as necessary to level but never sags like traditional goosenecks.
  4. The Lace-rail – Channel-Iron for durability and versatility with no notches or cut-outs for maximum strength. Includes stake-pockets and pipe-spools.
  5. The Box – It’s big and roomy. The lid is curved for added rigidity and gas spring assisted for easy operation.
  6. The Steps – The retractable front deck steps solve the common issue of traditional front deck steps being bent in low clearance situations. The mid-deck side turn signal step makes for easy access when equipment is loaded.
  7. The I-Beams – We engineer the beams, optimize them, and build them for each trailer configuration just like semi trailer manufacturers have been for decades. Our I-beam frames are taller, stronger, and lighter than your neighbor’s. 14-18” tall. Standard steel bends at 36 ksi. Our beams are built using steel rated at 50 ksi minimum.
